TITLE: NON-COORDINATING ANION TYPE BENZIMIDAZOLIUM

ACTIVATORS

INVENTORS: Catherine A. Faler, Margaret T. Whalley, and John R. Hagadom

FIELD

[0001] The present disclosure provides borate activators, a process for producing borate activators in aliphatic and alicyclic solvents, catalyst systems comprising such activators, and processes for polymerizing olefins using such activators. In particular, non-coordinating anion type activators comprising a benzimidazolium moiety.

BACKGROUND

[0002] Polyolefins are widely used commercially because of their robust physical properties. Polyolefins are typically prepared with a catalyst that polymerizes olefin monomers. Therefore, there is interest in finding new catalysts and catalyst systems that provide polymers having improved properties.

[0003] Catalysts for olefin polymerization are often based on metallocenes as catalyst precursors, which are activated either with an alumoxane or an activator containing a non coordinating anion. A non-coordinating anion, such as tetrakis(pentafluorophenyl)borate, is capable of stabilizing the resulting metal cation of the catalyst. Because such activators are fully ionized and the corresponding anion is highly non-coordinating, such activators can be effective as olefin polymerization catalyst activators. However, because they are ionic salts, such activators are insoluble in aliphatic hydrocarbons and only sparingly soluble in aromatic hydrocarbons. It is desirable to conduct most polymerizations of a-olefins in aliphatic hydrocarbon solvents due to the compatibility of such solvents with the olefin monomer and to reduce the aromatic hydrocarbon content of the resulting polymer product. Typically, ionic salt activators are added to such polymerizations in the form of a solution in an aromatic solvent such as toluene. The use of even a small quantity of such an aromatic solvent for this purpose is undesirable since it must be removed in a post-polymerization devolatilization step and separated from other volatile components, which is a process that adds significant cost and complexity to any commercial process. In addition, the activators often exist in the form of an oily, intractable material which is not readily handled and metered or precisely incorporated into the reaction mixture. [0004] In addition, polymer products, such as isotactic polypropylene, formed using such activators can have lower molecular weights (e.g., Mw less than about 100,000) and a high melt temperature (Tm) (e.g., Tm greater than about 110°C).

[0005] US 5,919,983 discloses polymerization of ethylene and octene using a catalyst system comprising [(Ci8)2MeN)]⁺[B(PhF5)4] activator having four fluoro-phenyl groups bound to the boron atom and two linear Cie groups bound to the nitrogen, as well as describing other linear groups at column 3, line 51 et seq.

[0006] US 8,642,497 discloses the preparation of N,N-dimethylanilinium tetrakis(heptafluoronaphth-2-yl)borate anion.

[0007] US 2003/0013913 (granted as US 7,101,940) discloses various activators such as N,N-dimethylcyclohexylammoniumtetrakis(pentafluorophenyl)borate [0070], and N,N- diethy lbenzy lammoniumtetrakis(pentafluoropheny l)borate [0124] .

[0008] US 2002/0062011 discloses phenyl dioctadecylammonium(hydroxyphenyl) tris(pentafluorophenyl) borate at paragraph [0200] and (pentafluorophenyl) dioctadecylammonium tetrakis(pentafluorophenyl) borate at paragraph [0209]

[0009] US 7,799,879, US 7,985,816, US 8,580,902, US 8,835,587, and W02010/014344 describe ammonium borate activators that include some that use a tetrakis(heptafluoronaphth- 2-yl)borate anion.

[0010] There is a need for activators that are soluble in aliphatic hydrocarbons and capable of producing polyolefins having a high molecular weight and high melt temperature. Likewise, there is aneed for activators that are soluble in aliphatic hydrocarbons and capable of producing polyolefins at high activity levels where the polymers preferably have high molecular weight and/or high melt temperature.

DETAILED DESCRIPTION

Definitions

[0020] Unless otherwise noted all melt temperatures (Tm) are DSC second melt and are determined using the following DSC procedure according to ASTM D3418-03. Differential scanning calorimetric (DSC) data are obtained using a TA Instruments model Q200 machine. Samples weighing about 5 to about 10 mg are sealed in an aluminum hermetic sample pan. The DSC data are recorded by first gradually heating the sample to about 200°C at a rate of about 10°C/minute. The sample is kept at about 200°C for about 2 minutes, then cooled to about -90°C at a rate of about 10° /minute, followed by an isothermal for about 2 minutes and heating to about 200°C at about 10°C/minute. Both the first and second cycle thermal events are recorded. The melting points reported herein are obtained during the second heating/cooling cycle unless otherwise noted.

[0021] All molecular weights are weight average (Mw) unless otherwise noted. All molecular weights are reported in g/mol unless otherwise noted. Melt index (MI) also referred to as 12, reported in g/10 min, is determined according to ASTM D-1238, 190°C, 2.16 kg load. High load melt index (HLMI) also referred to as 121, reported in g/10 min, is determined according to ASTM D-1238, 190°C, 21.6 kg load. Melt index ratio (MIR) is MI divided by HLMI as determined by ASTM D1238.

[0022] The specification describes catalysts that can be transition metal complexes. The term complex is used to describe molecules in which an ancillary ligand is coordinated to a central transition metal atom. The ligand is bulky and stably bonded to the transition metal so as to maintain its influence during use of the catalyst, such as polymerization. The ligand may be coordinated to the transition metal by covalent bond and/or electron donation coordination or intermediate bonds. The transition metal complexes are generally subjected to activation to perform their polymerization or oligomerization function using an activator which is believed to create a cation as a result of the removal of an anionic group, often referred to as a leaving group, from the transition metal.

[0023] For the purposes of the present disclosure, the numbering scheme for the Periodic Table Groups is the "New" notation as described in Chemical and Engineering News, 63(5), pg. 27 (1985). Therefore, a“Group 8 metal” is an element from Group 8 of the Periodic Table, e.g., Fe, and so on. [0024] The following abbreviations are used through this specification:

[0034] The terms“alkyl radical,”“alkyl moiety”, and“alkyl” are used interchangeably throughout this disclosure. For purposes of this disclosure, "alkyl radicals" are defined to be Ci-Cioo alkyls that may be linear, branched, or cyclic.

[0035] The term "branched alkyl" means that the alkyl group contains a tertiary or quaternary carbon (a tertiary' carbon is a carbon atom hound to three other carbon atoms. A quaternary_' carbon is a carbon atom bound to four other carbon atoms). For example, 3,5,5 trimethylhexylphenyl is an alkyl group (hexyl) having three methyl branches (hence, one tertiary and one quaternary carbon) and thus is a branched alkyl bound to a phenyl group.

[0036] The term "alkenyl" means a straight-chain, branched-chain, or cyclic hydrocarbon radical having one or more carbon-carbon double bonds. These alkenyl radicals may be substituted. Examples of suitable alkenyl radicals can include ethenyl, propenyl, allyl, 1,4- butadienyl cyclopropenyl, cyclobutenyl, cyclopentenyl, cyclohexenyl, cyclooctenyl and the like.

Examples of suitable alkyl ether radicals can include methoxy, ethoxy, n-propoxy, iso-propoxy, n-butoxy, iso-butoxy, sec- butoxy, tert-butoxy, phenoxy, and the like. [0039] The term "aryloxy" or“aryloxide” means an aryl ether radical wherein the term aryl is as defined herein.

[0040] The term "aryl" or "aryl group" means a carbon-containing aromatic ring such as phenyl. Likewise, heteroaryl means an aryl group where a ring carbon atom (or two or three ring carbon atoms) has been replaced with a heteroatom, such as N, O, or S. As used herein, the term "aromatic" also refers to pseudoaromatic heterocycles which are heterocyclic substituents that have similar properties and structures (nearly planar) to aromatic heterocyclic ligands but are not by definition aromatic.

[0041] A“perfluoro” substituted moiety, e.g., a perfluoro substituted naphthyl moiety, refers to a radical in which each available hydrogen atom of the radical or moiety is substituted with a fluorine atom.

[0042] Heterocyclic means a cyclic group where a ring carbon atom (or two or three ring carbon atoms) has been replaced with a heteroatom, such as N, O, or S. A heterocyclic ring is a ring having a heteroatom in the ring structure as opposed to a heteroatom substituted ring where a hydrogen on a ring atom is replaced with a heteroatom. For example, tetrahydrofuran is a heterocyclic ring and 4-N,N-dimethylamino-phenyl is a heteroatom substituted ring.

[0043] Substituted heterocyclic means a heterocyclic group where at least one hydrogen atom of the heterocyclic radical has been substituted with at least a non-hydrogen group, such as a hydrocarbyl group, a heteroatom, or a heteroatom containing group, such as halogen (such as Br, Cl, F or I) or at least one functional group such as -NR*₂, -OR*, -SeR*, -TeR*, -PR*₂. -ASR*₂, -SbR*₂, -SR*, -BR*2, -SiR*, -SiR*₃, -GeR*, -GeR*₃, -SnR*, -SnR*₃, -PbR*₃, and the like, where each R* is independently a hydrocarbyl or halocarbyl radical.

[0044] A substituted aryl is an aryl group where at least one hydrogen atom of the aryl radical has been substituted with at least a non-hydrogen group, such as a hydrocarbyl group, a heteroatom, or a heteroatom containing group, such as halogen (such as Br, Cl, F or I) or at least one functional group such as -NR*₂, -OR*, -SeR*, -TeR*, -PR*₂. -AsR*₂, -SbR*₂, -SR*, -BR*2, -SiR*, -SiR*₃, -GeR*, -GeR*₃, -SnR*, -SnR*₃, -PbR*₃, and the like, where each R* is independently a hydrocarbyl or halocarbyl radical, and two or more R* may join together to form a substituted or unsubstituted saturated, partially unsaturated or aromatic cyclic or polycyclic ring structure, or where at least one heteroatom has been inserted within a hydrocarbyl ring, for example 3,5-dimethylphenyl is a substituted aryl group.

[0045] The term "substituted phenyl," or "substituted phenyl group" means a phenyl group having one or more hydrogen groups replaced by a hydrocarbyl, substituted hydrocarbyl, heteroatom or heteroatom containing group, such as halogen (such as Br, Cl, F or I) or at least one functional group such as -NR*₂, -OR*, -SeR*, -TeR*, -PR*₂, -AsR*₂, -SbR*₂, -SR*, -BR*₂, -SiR*, -SiR*3, -GeR*, -GeR*3, -SnR*, -SnR*₃, -PbR*3, and the like, where each R* is independently a hydrocarbyl, halogen, or halocarbyl radical. Preferably the "substituted phenyl" group is represented by the formula:

where each of R¹⁷, R¹⁸, R¹⁹, R²⁰, and R²¹ is independently selected from hydrogen, C1-C40 hydrocarbyl or C1-C40 substituted hydrocarbyl, a heteroatom, such as halogen, or a heteroatom- containing group (provided that at least one of R¹⁷, R¹⁸, R¹⁹, R²⁰, and R²¹ is not H), or a combination thereof.

[0046] A "fluorophenyl" or "fluorophenyl group" is a phenyl group substituted with one, two, three, four or five fluorine atoms.

[0047] The term "arylalkyl" means an aryl group where a hydrogen has been replaced with an alkyl or substituted alkyl group. For example, 3,5'-di-tert-butyl-phenyl indenyl is an indene substituted with an arylalkyl group. When an arylalkyl group is a substituent on another group, it is bound to that group via the aryl. For example in Formula (AI), the aryl portion is bound to E.

[0048] The term "alkylaryl" means an alkyl group where a hydrogen has been replaced with an aryl or substituted aryl group. For example, phenethyl indenyl is an indene substituted with an ethyl group bound to a benzene group. When an alkylaryl group is a substituent on another group, it is bound to that group via the alkyl.

[0049] Reference to an alkyl, alkenyl, alkoxide, or aryl group without specifying a particular isomer (e.g., butyl) expressly discloses all isomers (e.g., n-butyl, iso-butyl, sec-butyl, and tert-butyl), unless otherwise indicated.

[0050] The term "ring atom" means an atom that is part of a cyclic ring structure.

Accordingly, a benzyl group has six ring atoms and tetrahydrofuran has 5 ring atoms. [0051] For purposes of the present disclosure, a“catalyst system” is a combination of at least one catalyst compound, an activator, and an optional support material. The catalyst systems may further comprise one or more additional catalyst compounds. For the purposes of the present disclosure, when catalyst systems are described as comprising neutral stable forms of the components, it is well understood by one of ordinary skill in the art, that the ionic form of the component is the form that reacts with the monomers to produce polymers. Catalysts of the presented disclosure and activators represented by formula (I) are intended to embrace ionic forms in addition to the neutral forms of the compounds.

[0052] “Complex” as used herein, is also often referred to as catalyst precursor, precatalyst, catalyst, catalyst compound, transition metal compound, or transition metal complex. These words are used interchangeably.

[0053] A scavenger is a compound that is typically added to facilitate polymerization by scavenging impurities. Some scavengers may also act as activators and may be referred to as co-activators. A co-activator, that is not a scavenger, may also be used in conjunction with an activator in order to form an active catalyst. In some embodiments a co-activator can be pre mixed with the transition metal compound to form an alkylated transition metal compound.

[0054] In the description herein, a catalyst may be described as a catalyst precursor, a pre catalyst compound, a catalyst compound or a transition metal compound, and these terms are used interchangeably. A polymerization catalyst system is a catalyst system that can polymerize monomers into polymer. An“anionic ligand” is a negatively charged ligand which donates one or more pairs of electrons to a metal ion. A“neutral donor ligand” is a neutrally charged ligand which donates one or more pairs of electrons to a metal ion.

[0055] A metallocene catalyst is defined as an organometallic compound with at least one p-bound cyclopentadienyl moiety or substituted cyclopentadienyl moiety (such as substituted or unsubstituted Cp, Ind, or Flu) and more frequently two (or three) p-bound cyclopentadienyl moieties or substituted cyclopentadienyl moieties (such as substituted or unsubstituted Cp, Ind, or Flu). (Cp = cyclopentadienyl, Ind= indenyl, Flu=fluorenyl).

[0056] For purposes of the present disclosure, in relation to catalyst compounds, the term “substituted” means that a hydrogen group has been replaced with a hydrocarbyl group, a heteroatom, or a heteroatom containing group. For example, methyl cyclopentadiene (Cp) is a Cp group substituted with a methyl group.

[0057] “Catalyst productivity” is a measure of how many grams of polymer (P) are produced using a polymerization catalyst comprising W g of catalyst (cat), over a period of time of T hours; and may be expressed by the following formula: P/(T x W) and expressed in units of gPgcar'hr¹. "Conversion" is the amount of monomer that is converted to polymer product and is reported as mol% and is calculated based on the polymer yield and the amount of monomer fed into the reactor. "Catalyst activity" is a measure of the level of activity of the catalyst and is reported as the mass of product polymer (P) produced per mole (or mmol) of catalyst (cat) used (kgP/molcat or gP/mmolCat), and catalyst activity can also be expressed per unit of time, for example, per hour (hr), e.g., (Kg/mmol h).

[0058] For purposes herein an“olefin,” alternatively referred to as“alkene,” is a linear, branched, or cyclic compound comprising carbon and hydrogen having at least one double bond. For purposes of this specification and the claims appended thereto, when a polymer or copolymer is referred to as comprising an olefin, the olefin present in such polymer or copolymer is the polymerized form of the olefin. For example, when a copolymer is said to have a "propylene" content of 35 wt% to 55 wt%, it is understood that the mer unit in the copolymer is derived from propylene in the polymerization reaction and the derived units are present at 35 wt% to 55 wt%, based upon the weight of the copolymer.

[0059] For purposes herein a“polymer” has two or more of the same or different monomer (“mer”) units. A“homopolymer” is a polymer having mer units that are the same. A “copolymer” is a polymer having two or more mer units that are different from each other. A “terpolymer” is a polymer having three mer units that are different from each other.“Different” in reference to mer units indicates that the mer units differ from each other by at least one atom or are different isomerically. Accordingly, copolymer, as used herein, can include terpolymers and the like. An oligomer is typically a polymer having a low molecular weight, such an Mn of less than 25,000 g/mol, or less than 2,500 g/mol, or a low number of mer units, such as 75 mer units or less or 50 mer units or less. An "ethylene polymer" or "ethylene copolymer" is a polymer or copolymer comprising at least 50 mol% ethylene derived units, a "propylene polymer" or "propylene copolymer" is a polymer or copolymer comprising at least 50 mole% propylene derived units, and so on.

[0060] As used herein, Mn is number average molecular weight, Mw is weight average molecular weight, and Mz is z average molecular weight, wt% is weight percent, and mol% is mole percent. Molecular weight distribution (MWD), also referred to as polydispersity index (PDI), is defined to be Mw divided by Mn.

[0061] The term "continuous" means a system that operates without interruption or cessation for a period of time, such as where reactants are continually fed into a reaction zone and products are continually or regularly withdrawn without stopping the reaction in the reaction zone. For example, a continuous process to produce a polymer would be one where the reactants are continually introduced into one or more reactors and polymer product is continually withdrawn.

[0062] A “solution polymerization” means a polymerization process in which the polymerization is conducted in a liquid polymerization medium, such as an inert solvent or monomer(s) or their blends. A solution polymerization is typically homogeneous. A homogeneous polymerization is one where the polymer product is dissolved in the polymerization medium. Such systems are typically not turbid as described in Oliveira, J. V. et al. (2000)“High-Pressure Phase Equilibria for Polypropylene-Hydrocarbon Systems,” Ind. Eng. Chem. Res., v.39, pp. 4627-4633.

[0063] A bulk polymerization means a polymerization process in which the monomers and/or comonomers being polymerized are used as a solvent or diluent using little or no inert solvent or diluent. A small fraction of inert solvent might be used as a carrier for catalyst and scavenger. A bulk polymerization system contains less than about 25 wt% of inert solvent or diluent, such as less than about 10 wt%, such as less than about 1 wt%, such as 0 wt%.

In one or more embodiments, the process is performed in gas phase or slurry phase.

Non-Coordinating Anion (NCA) Activators

[0096] Noncoordinating anion (NCA) means an anion either that does not coordinate to the catalyst metal cation or that does coordinate to the metal cation, but only weakly. The term NCA is also defined to include multicomponent NCA-containing activators, such as alkyl substituted benzimidazolium tetrakis(perfluoronaphthyl)borate, that contain an acidic cationic group and the non-coordinating anion. The term NCA is also defined to include neutral Lewis acids, such as tris(pentafluoronaphthyl)boron, that can react with a catalyst to form an activated species by abstraction of an anionic group. An NCA coordinates weakly enough that a neutral Lewis base, such as an olefinically or acetylenically unsaturated monomer can displace it from the catalyst center. Any metal or metalloid that can form a compatible, weakly coordinating complex may be used or contained in the noncoordinating anion. Suitable metals can include aluminum, gold, and platinum. Suitable metalloids can include boron, aluminum, phosphorus, and silicon. The term non-coordinating anion activator includes neutral activators, ionic activators, and Lewis acid activators.

[0097] “Compatible” non-coordinating anions can be those which are not degraded to neutrality when the initially formed complex decomposes. Further, the anion will not transfer an anionic substituent or fragment to the cation so as to cause it to form a neutral transition metal compound and a neutral by-product from the anion. Non-coordinating anions useful in accordance with the present disclosure are those that are compatible, stabilize the transition metal cation in the sense of balancing its ionic charge at +1, and yet retain sufficient lability to permit displacement during polymerization. Activators

[0098] The present disclosure provides activators, which are alkyl substituted benzimidazolium metallate or metalloid activator compounds, comprising benzimidazolium groups with hydrocarbyl substitutions, preferably N substituted long-chain aliphatic hydrocarbyl groups combined with metallate or metalloid anions, such as borates or aluminates. When an activator of the present disclosure is used with a catalyst compound (such as a group 4 metallocene compound) in an olefin polymerization, a polymer can be formed having a higher molecular weight and melt temperature than polymers formed using comparative activators. Likewise, when an activator of the present disclosure where R² is methyl, preferably having 6 or more carbon atoms, is used with a group 4 metallocene catalyst in an olefin polymerization, the catalyst system activity is substantially better than comparative activators and can form polymers having a higher molecular weight and/or melt temperature vs. polymers formed using comparative activators. In addition, it has been discovered that in embodiments, activators of the present disclosure are soluble in aliphatic and/or alicyclic solvents. In at least one embodiment of the invention, the activator is represented by formula (AI):

[0102] The terms“cocatalyst” and“activator” are used herein interchangeably and are defined to be any compound which can activate any one of the catalyst compounds of the present disclosure by converting the neutral catalyst compound to a catalytically active catalyst compound cation.

[0103] Catalyst systems of the present disclosure may be formed by combining the catalysts with activators in any suitable manner, including by supporting them for use in slurry or gas phase polymerization.

Formula 7

wherein:

M* is a group 13 atom, preferably B or Al, preferably B;

each R¹¹ is, independently, a halide, preferably a fluoride;

each R¹² is, independently, a halide, a Ce to C20 substituted aromatic hydrocarbyl group or a siloxy group of the formula -0-Si-R^a, where R^a is a Ci to C20 hydrocarbyl or hydrocarbylsilyl group, preferably R¹² is a fluoride or a perfluorinated phenyl group;

Preferably the anion has a molecular weight of greater than 700 g/mol, and, preferably, at least three of the substituents on the M* atom each have a molecular volume of greater than 180 cubic A.

[0116] "Molecular volume" is used herein as an approximation of spatial steric bulk of an activator molecule in solution. Comparison of substituents with differing molecular volumes allows the substituent with the smaller molecular volume to be considered "less bulky" in comparison to the substituent with the larger molecular volume. Conversely, a substituent with a larger molecular volume may be considered "more bulky" than a substituent with a smaller molecular volume. [0117] Molecular volume may be calculated as reported in Girolami, G. S. (1994) "A Simple "Back of the Envelope" Method for Estimating the Densities and Molecular Volumes of Liquids and Solids," Journal of Chemical Education, v.71(ll), pp. 962-964. Molecular volume (MV), in units of cubic A, is calculated using the formula: MV = 8.3V_S, where V_s is the scaled volume. V_s is the sum of the relative volumes of the constituent atoms, and is calculated from the molecular formula of the substituent using Table 1 below of relative volumes. For fused rings, the V_s is decreased by 7.5% per fused ring. The Calculated Total MV of the anion is the sum of the MV per substituent, for example, the MV of perfluorophenyl is 183 A³, and the Calculated Total MV for tetrakis(perfluorophenyl)borate is four times 183 A³, or 732 A³.

Non-Metallocene Catalyst Compounds

[0164] Transition metal complexes for polymerization processes can include any olefin polymerization catalyst. Suitable catalyst components may include “non-metallocene complexes” that are defined to be transition metal complexes that do not feature a cyclopentadienyl anion or substituted cyclopentadienyl anion donors (e.g., cyclopentadienyl, fluorenyl, indenyl, methylcyclopentadienyl). Examples of families of non-metallocene complexes that may be suitable can include late transition metal pyridylbisimines (e.g., US 7,087,686), group 4 pyridyldiamidos (e.g., US 7,973,116), quinobnyldiamidos (e.g., US Pub. No. 2018/0002352 Al), pyridylamidos (e.g., US 7,087,690), phenoxyimines (e.g., Makio, H. et al. (2009) “Development and Application of FI Catalysts for Olefin Polymerization: Unique Catalysis and Distinctive Polymer Formation,” Accounts of Chemical Research, v.42(10), pp. 1532-1544), and bridged bi-aromatic complexes (e.g., US 7,091,292), the disclosures of which are incorporated herein by reference.

[0165] Catalyst complexes that are suitable for use in combination with the activators described herein include: pyridyldiamido complexes; quinobnyldiamido complexes; phenoxyimine complexes; bisphenolate complexes; cyclopentadienyl-amidinate complexes; and iron pyridyl bis(imine) complexes or any combination thereof, including any combination with metallocene complexes.

[0166] The term “pyridyldiamido complex” or “pyridyldiamide complex” or “pyridyldiamido catalyst” or“pyridyldiamide catalyst” refers to a class of coordination complexes described in US Pat. No. 7,973,116B2, US 2012/0071616A1, US 2011/0224391 Al, US 2011/0301310A1, US 2015/0141601A1, US 6,900,321 and US 8,592,615 that feature a dianionic tridentate ligand that is coordinated to a metal center through one neutral Lewis basic donor atom (e.g., a pyridine group) and a pair of anionic amido or phosphido (i.e., deprotonated amine or phosphine) donors. In these complexes the pyridyldiamido ligand is coordinated to the metal with the formation of one five membered chelate ring and one seven membered chelate ring. It is possible for additional atoms of the pyridyldiamido ligand to be coordinated to the metal without affecting the catalyst function upon activation; an example of this could be a cyclometalated substituted aryl group that forms an additional bond to the metal center. [0167] The term “quinolinyldiamido complex” or “quinolinyldiamido catalyst” or “quinolinyldiamide complex” or“quinolinyldiamide catalyst” refers to a related class of pyridyldiamido complex/catalyst described in US 2018/0002352 where a quinolinyl moiety is present instead of a pyridyl moiety.

[0168] The term“phenoxyimine complex” or“phenoxyimine catalyst” refers to a class of coordination complexes described in EP 0874005 that feature a monoanionic bidentate ligand that is coordinated to a metal center through one neutral Lewis basic donor atom (e.g., an imine moiety) and an anionic aryloxy (i.e., deprotonated phenoxy) donor. Typically, two of these bidentate phenoxyimine ligands are coordinated to a group 4 metal to form a complex that is useful as a catalyst component.

[0169] The term“bisphenolate complex” or“bisphenolate catalyst” refers to a class of coordination complexes described in US 6,841,502, WO 2017/004462, and WO 2006/020624 that feature a dianionic tetradentate ligand that is coordinated to a metal center through two neutral Lewis basic donor atoms (e.g., oxygen bridge moieties) and two anionic aryloxy (i.e., deprotonated phenoxy) donors.

[0170] The term“cyclopentadienyl-amidinate complex” or“cyclopentadienyl-amidinate catalyst” refers to a class of coordination complexes described in US 8,188,200 that typically feature a group 4 metal bound to a cyclopentadienyl anion, a bidentate amidinate anion, and a couple of other anionic groups.

[0171] The term“iron pyridyl bis(imine) complex” refers to a class of iron coordination complexes described in US 7,087,686 that typically feature an iron metal center coordinated to a neutral, tridentate pyridyl bis(imine) ligand and two other anionic ligands.

[0172] Non-metallocene complexes can include iron complexes of tridentate pyridylbisimine ligands, zirconium and hafnium complexes of pyridylamido ligands, zirconium and hafnium complexes of tridentate pyridyldiamido ligands, zirconium and hafnium complexes of tridentate quinolinyldiamido ligands, zirconium and hafnium complexes of bidentate phenoxyimine ligands, and zirconium and hafnium complexes of bridged bi aromatic ligands.

[0173] Suitable non-metallocene complexes can include zirconium and hafnium non metallocene complexes. In at least one embodiment, non-metallocene complexes for the present disclosure include group 4 non-metallocene complexes including two anionic donor atoms and one or two neutral donor atoms. Suitable non- metallocene complexes for the present disclosure include group 4 non-metallocene complexes including an anionic amido donor. Suitable non-metallocene complexes for the present disclosure include group 4 non metallocene complexes including an anionic aryloxide donor atom. Suitable non-metallocene complexes for the present disclosure include group 4 non-metallocene complexes including two anionic aryloxide donor atoms and two additional neutral donor atoms.

In many embodiments, R⁶ and R⁷ are absent. R* may be absent, or may be a hydrogen, a Group 14 atom containing group, a halogen, or a heteroatom containing group.

[0224] By "formal charge of the YZL or YZL' ligand," it is meant the charge of the entire ligand absent the metal and the leaving groups X. By "R¹ and R² may also be interconnected" it is meant that R¹ and R² may be directly bound to each other or may be bound to each other through other groups. By "R⁴ and R⁵ may also be interconnected" it is meant that R⁴ and R⁵ may be directly bound to each other or may be bound to each other through other groups.

[0227] In preferred embodiments, the catalyst compounds described in

PCT/US2018/051345, filed September 17, 2018 may be used with the activators described herein, particularly the catalyst compounds described at Page 16 to Page 32 of the application as filed.

[0228] In some embodiments, a co-activator is combined with the catalyst compound (such as halogenated catalyst compounds described above) to form an alkylated catalyst compound. Organoaluminum compounds which may be utilized as co-activators include, for example, trialkyl aluminum compounds, such as trimethylaluminum, triethylaluminum, triisobutylaluminum, tri-n-hexylaluminum, tri-n-octylaluminum, and the like, or alumoxanes.

[0229] In some embodiments, two or more different catalyst compounds are present in the catalyst system used herein. In some embodiments, two or more different catalyst compounds are present in the reaction zone where the process(es) described herein occur. When two transition metal compound-based catalysts are used in one reactor as a mixed catalyst system, the two transition metal compounds are preferably chosen such that the two are compatible. A simple screening method such as by ¾ or ¹³C NMR, known to those of ordinary skill in the art, can be used to determine which transition metal compounds are compatible. It is preferable to use the same activator for the transition metal compounds; however, two different activators can be used in combination. If one or more transition metal compounds contain an anionic ligand as a leaving group which is not a hydride, hydrocarbyl, or substituted hydrocarbyl, then the alumoxane or other alkyl aluminum is typically contacted with the transition metal compounds prior to addition of the non-coordinating anion activator.

[0230] The two transition metal compounds (pre-catalysts) may be used in any ratio. Preferred molar ratios of (A) transition metal compound to (B) transition metal compound fall within the range of (A:B) 1 : 1000 to 1000: 1, alternatively 1 : 100 to 500: 1, alternatively 1: 10 to 200: 1, alternatively 1: 1 to 100: 1, and alternatively 1: 1 to 75: 1, and alternatively 5: 1 to 50: 1. The particular ratio chosen will depend on the exact pre-catalysts chosen, the method of activation, and the end product desired. In a particular embodiment, when using the two pre catalysts, where both are activated with the same activator, useful mole percents, based upon the molecular weight of the pre-catalysts, are 10 to 99.9% A to 0.1 to 90% B, alternatively 25 to 99% A to 0.5 to 50% B, alternatively 50 to 99% A to 1 to 25% B, and alternatively 75 to 99% A to 1 to 10%B.

Support Materials

[0231] In embodiments herein, the catalyst system may comprise a support material. In at least one embodiment, the support material is a porous support material, for example, talc, or inorganic oxides. Other support materials include zeolites, clays, organoclays, or any other suitable organic or inorganic support material and the like, or mixtures thereof.

[0232] In at least one embodiment, the support material is an inorganic oxide. Suitable inorganic oxide materials for use in catalyst systems herein include Groups 2, 4, 13, and 14 metal oxides, such as silica, alumina, and mixtures thereof. Other inorganic oxides that may be employed either alone or in combination with the silica, or alumina are magnesia, titania, zirconia, and the like. Other suitable support materials, however, can be used, for example, functionalized polyolefins, such as polypropylene. Supports include magnesia, titania, zirconia, montmorillonite, phyllosilicate, zeolites, talc, clays, and the like. Also, combinations of these support materials may be used, for example, silica-chromium, silica-alumina, silica-titania, and the like. Support materials include AI2O3, Zr02, S1O2, S1O2/AI2O3, Si02/Ti02, silica clay, silicon oxide/clay, or mixtures thereof.

[0233] The support material, such as an inorganic oxide, can have a surface area of from 10 m²/g to 700 m²/g, pore volume in the range of from 0.1 cc/g to 4.0 cc/g and average particle size in the range of from 5 pm to 500 pm. In at least one embodiment, the surface area of the support material is in the range of from 50 m²/g to 500 m²/g, pore volume of from 0.5 cc/g to 3.5 cc/g and average particle size of from 10 pm to 200 pm. In at least one embodiment, the surface area of the support material is in the range is from 100 m²/g to 400 m²/g, pore volume from 0.8 cc/g to 3.0 cc/g and average particle size is from 5 pm to 100 pm. The average pore size of the support material useful in the present disclosure is in the range of from 10 A to 1000 A, such as 50 A to 500 A, such as 75 A to 350 A. In some embodiments, the support material is a high surface area, amorphous silica (surface area=300 m²/gm; pore volume of 1.65 cm³/gm). Exemplary silicas are marketed under the tradenames of DAVISON 952 or DAVISON 955 by the Davison Chemical Division of W.R. Grace and Company. In other embodiments DAVISON 948 is used.

[0234] The support material should be dry, that is, substantially free of absorbed water. Drying of the support material can be effected by heating or calcining at 100°C to 1,000°C, such as at least about 600°C. When the support material is silica, it is heated to at least 200°C, such as 200°C to 850°C, such as at about 600°C; and for a time of 1 minute to about 100 hours, from 12 hours to 72 hours, or from 24 hours to 60 hours. The calcined support material should have at least some reactive hydroxyl (OH) groups to produce supported catalyst systems of the present disclosure. The calcined support material is then contacted with at least one polymerization catalyst comprising at least one catalyst compound and an activator.

[0235] The support material, having reactive surface groups, typically hydroxyl groups, is slurried in a non-polar solvent and the resulting slurry is contacted with a solution of a catalyst compound and an activator. In some embodiments, the slurry of the support material is first contacted with the activator for a period of time in the range of from 0.5 hours to 24 hours, from 2 hours to 16 hours, or from 4 hours to 8 hours. The solution of the catalyst compound is then contacted with the isolated support/activator. In some embodiments, the supported catalyst system is generated in situ. In at least one embodiment, the slurry of the support material is first contacted with the catalyst compound for a period of time in the range of from 0.5 hours to 24 hours, from 2 hours to 16 hours, or from 4 hours to 8 hours. The slurry of the supported catalyst compound is then contacted with the activator solution.

[0236] The mixture of the catalyst, activator and support is heated to 0°C to 70°C, such as to 23°C to 60°C, such as at room temperature. Contact times typically range from 0.5 hours to 24 hours, from 2 hours to 16 hours, or from 4 hours to 8 hours.

[0237] Suitable non-polar solvents are materials in which all of the reactants used herein, e.g., the activator, and the catalyst compound, are at least partially soluble and which are liquid at room temperature. Non-limiting example non-polar solvents are alkanes, such as isopentane, hexane, n-heptane, octane, nonane, and decane, cycloalkanes, such as cyclohexane, aromatics, such as benzene, toluene, and ethylbenzene.

[0238] In at least one embodiment, the support material comprises a support material treated with an electron-withdrawing anion. The support material can be silica, alumina, silica- alumina, silica-zirconia, alumina-zirconia, aluminum phosphate, heteropolytungstates, titania, magnesia, boria, zinc oxide, mixed oxides thereof, or mixtures thereof; and the electron- withdrawing anion is selected from fluoride, chloride, bromide, phosphate, triflate, bisulfate, sulfate, or any combination thereof.

[0239] The electron-withdrawing component used to treat the support material can be any component that increases the Lewis or Bronsted acidity of the support material upon treatment (as compared to the support material that is not treated with at least one electron-withdrawing anion). In at least one embodiment, the electron-withdrawing component is an electron- withdrawing anion derived from a salt, an acid, or other compound, such as a volatile organic compound, that serves as a source or precursor for that anion. Electron-withdrawing anions can be sulfate, bisulfate, fluoride, chloride, bromide, iodide, fluorosulfate, fluoroborate, phosphate, fluorophosphate, trifluoroacetate, triflate, fluorozirconate, fluorotitanate, phospho-tungstate, or mixtures thereof, or combinations thereof. An electron-withdrawing anion can be fluoride, chloride, bromide, phosphate, triflate, bisulfate, or sulfate, or any combination thereof, at least one embodiment of this disclosure. In at least one embodiment, the electron-withdrawing anion is sulfate, bisulfate, fluoride, chloride, bromide, iodide, fluorosulfate, fluoroborate, phosphate, fluorophosphate, trifluoroacetate, triflate, fluorozirconate, fluorotitanate, or combinations thereof.

[0240] Thus, for example, the support material suitable for use in the catalyst systems of the present disclosure can be one or more of fluorided alumina, chlorided alumina, bromided alumina, sulfated alumina, fluorided silica-alumina, chlorided silica-alumina, bromided silica- alumina, sulfated silica-alumina, fluorided silica-zirconia, chlorided silica-zirconia, bromided silica-zirconia, sulfated silica-zirconia, fluorided silica-titania, fluorided silica-coated alumina, sulfated silica-coated alumina, phosphated silica-coated alumina, or combinations thereof. In at least one embodiment, the activator-support can be, or can comprise, fluorided alumina, sulfated alumina, fluorided silica-alumina, sulfated silica-alumina, fluorided silica-coated alumina, sulfated silica-coated alumina, phosphated silica-coated alumina, or combinations thereof. In another embodiment, the support material includes alumina treated with hexafluorotitanic acid, silica-coated alumina treated with hexafluorotitanic acid, silica-alumina treated with hexafluorozirconic acid, silica-alumina treated with trifluoroacetic acid, fluorided boria-alumina, silica treated with tetrafluoroboric acid, alumina treated with tetrafluoroboric acid, alumina treated with hexafluorophosphoric acid, or combinations thereof. Further, any of these activator-supports optionally can be treated with a metal ion. [0241] Nonlimiting examples of cations suitable for use in the present disclosure in the salt of the electron-withdrawing anion include anilinium, trialkyl anilinium, tetraalkyl anilinium, or combinations thereof.

[0242] Further, combinations of one or more different electron-withdrawing anions, in varying proportions, can be used to tailor the specific acidity of the support material to a desired level. Combinations of electron-withdrawing components can be contacted with the support material simultaneously or individually, and in any order that provides a desired chemically- treated support material acidity. For example, in at least one embodiment, two or more electron- withdrawing anion source compounds in two or more separate contacting steps.

[0243] In at least one embodiment of the present disclosure, one example of a process by which a chemically-treated support material is prepared is as follows: a selected support material, or combination of support materials, can be contacted with a first electron- withdrawing anion source compound to form a first mixture; such first mixture can be calcined and then contacted with a second electron-withdrawing anion source compound to form a second mixture; the second mixture can then be calcined to form a treated support material. In such a process, the first and second electron-withdrawing anion source compounds can be either the same or different compounds.

[0244] The method by which the oxide is contacted with the electron-withdrawing component, typically a salt or an acid of an electron-withdrawing anion, can include gelling, co-gelling, impregnation of one compound onto another, or combinations thereof. Following a contacting method, the contacted mixture of the support material, electron- withdrawing anion, and optional metal ion, can be calcined.

[0245] According to another embodiment of the present disclosure, the support material can be treated by a process comprising: (i) contacting a support material with a first electron- withdrawing anion source compound to form a first mixture; (ii) calcining the first mixture to produce a calcined first mixture; (iii) contacting the calcined first mixture with a second electron-withdrawing anion source compound to form a second mixture; and (iv) calcining the second mixture to form the treated support material.

A "reaction zone" also referred to as a "polymerization zone" is a vessel where polymerization takes place, for example a batch reactor. When multiple reactors are used in either series or parallel configuration, each reactor is considered as a separate polymerization zone. For a multi-stage polymerization in both a batch reactor and a continuous reactor, each polymerization stage is considered as a separate polymerization zone. In at least one embodiment, the polymerization occurs in one reaction zone.

[0266] Other additives may also be used in the polymerization, as desired, such as one or more scavengers, promoters, modifiers, chain transfer agents (such as diethyl zinc), reducing agents, oxidizing agents, hydrogen, aluminum alkyls, or silanes. Useful chain transfer agents are typically alkylalumoxanes, a compound represented by the formula AIR3, ZnR.2 (where each R is, independently, a C i-Cx aliphatic radical, such as methyl, ethyl, propyl, butyl, phenyl, hexyl, octyl or an isomer thereol) or a combination thereof, such as diethyl zinc, methylalumoxane, trimethylaluminum, triisobutylaluminum, trioctylaluminum, or a combination thereof.

Gas phase polymerization

[0267] Generally, in a fluidized gas bed process used for producing polymers, a gaseous stream containing one or more monomers is continuously cycled through a fluidized bed in the presence of a catalyst under reactive conditions. The gaseous stream is withdrawn from the fluidized bed and recycled back into the reactor. Simultaneously, polymer product is withdrawn from the reactor and fresh monomer is added to replace the polymerized monomer. (See, for example, US Pat. Nos. 4,543,399; 4,588,790; 5,028,670; 5,317,036; 5,352,749; 5,405,922; 5,436,304; 5,453,471; 5,462,999; 5,616,661; and 5,668,228; all of which are fully incorporated herein by reference.)

Slurry phase polymerization

[0268] A slurry polymerization process generally operates between 1 to about 50 atmosphere pressure range (15 psi to 735 psi, 103 kPa to 5,068 kPa) or even greater and temperatures in the range of 0°C to about 120°C. In a slurry polymerization, a suspension of solid, particulate polymer is formed in a liquid polymerization diluent medium to which monomer and comonomers, along with catalysts, are added. The suspension including diluent is intermittently or continuously removed from the reactor where the volatile components are separated from the polymer and recycled, optionally after a distillation, to the reactor. The liquid diluent used in the polymerization medium is typically an alkane having from 3 to 7 carbon atoms, such as a branched alkane. The medium employed should be liquid under the conditions of polymerization and relatively inert. When a propane medium is used, the process must be operated above the reaction diluent critical temperature and pressure. For example, a hexane or an isobutane medium is employed.

[0269] In at least one embodiment, a polymerization process is a particle form polymerization, or a slurry process, where the temperature is kept below the temperature at which the polymer goes into solution. Such technique is well known in the art and described in for instance US Pat. No. 3,248,179 which is fully incorporated herein by reference. The temperature in the particle form process can be from about 85°C to about 110°C. Two example polymerization methods for the slurry process are those using a loop reactor and those utilizing a plurality of stirred reactors in series, parallel, or combinations thereof. Non-limiting examples of slurry processes include continuous loop or stirred tank processes. Also, other examples of slurry processes are described in US Pat. No. 4,613,484, which is herein fully incorporated by reference.

[0270] In another embodiment, the slurry process is carried out continuously in a loop reactor. The catalyst, as a slurry in isohexane or as a dry free flowing powder, is injected regularly to the reactor loop, which is itself filled with circulating slurry of growing polymer particles in a diluent of isohexane containing monomer and optional comonomer. Hydrogen, optionally, may be added as a molecular weight control. (In one embodiment hydrogen is added from 50 ppm to 500 ppm, such as from 100 ppm to 400 ppm, such as 150 ppm to 300 ppm.) [0271] The reactor may be maintained at a pressure of 2,000 kPa to 5,000 kPa, such as from 3,620 kPa to 4,309 kPa, and at a temperature of from about 60°C to about 120°C depending on the desired polymer melting characteristics. Reaction heat is removed through the loop wall since much of the reactor is in the form of a double-jacketed pipe. The slurry is allowed to exit the reactor at regular intervals or continuously to a heated low-pressure flash vessel, rotary dryer and a nitrogen purge column in sequence for removal of the isohexane diluent and all unreacted monomer and comonomer. The resulting hydrocarbon free powder is then compounded for use in various applications.

[0272] Other additives may also be used in the polymerization, as desired, such as one or more scavengers, promoters, modifiers, chain transfer agents (such as diethyl zinc), reducing agents, oxidizing agents, hydrogen, aluminum alkyls, or silanes.

[0273] Useful chain transfer agents are typically alkylalumoxanes, a compound represented by the formula AIR3, ZnR2 (where each R is, independently, a C i-Cx hydrocarbyl, such as methyl, ethyl, propyl, butyl, penyl, hexyl octyl or an isomer thereol). Examples can include diethyl zinc, methylalumoxane, trimethylaluminum, triisobutylaluminum, trioctylaluminum, or a combination thereof.

Solution polymerization

[0274] A solution polymerization is a polymerization process in which the polymer is dissolved in a liquid polymerization medium, such as an inert solvent or monomer(s) or their blends. A solution polymerization is typically homogeneous. A homogeneous polymerization is one where the polymer product is dissolved in the polymerization medium. Such systems are typically not turbid as described in Oliveira, J. V. et al. (2000)“High-Pressure Phase Equilibria for Polypropylene-Hydrocarbon Systems” Ind. Eng. Chem. Res., \ .39. pp. 4627-4633. Generally, solution polymerization involves polymerization in a continuous reactor in which the polymer formed, and the starting monomer and catalyst materials supplied, are agitated to reduce or avoid concentration gradients and in which the monomer acts as a diluent or solvent or in which a hydrocarbon is used as a diluent or solvent. Suitable processes typically operate at temperatures from about 0°C to about 250°C, such as about 10°C to about 150°C, such as about 40°C to about 140°C, such as about 50°C to about 120°C, and at pressures of about 0.1 MPa or more, such as 2 MPa or more. The upper pressure limit is not critically constrained but typically can be about 200 MPa or less, such as 120 MPa or less. Temperature control in the reactor can generally be obtained by balancing the heat of polymerization and with reactor cooling by reactor jackets or cooling coils to cool the contents of the reactor, auto refrigeration, pre-chilled feeds, vaporization of liquid medium (diluent, monomers or solvent) or combinations of all three. Adiabatic reactors with pre-chilled feeds can also be used. The purity, type, and amount of solvent can be optimized for the maximum catalyst productivity for a particular type of polymerization. The solvent can be also introduced as a catalyst carrier. The solvent can be introduced as a gas phase or as a liquid phase depending on the pressure and temperature. Advantageously, the solvent can be kept in the liquid phase and introduced as a liquid. Solvent can be introduced in the feed to the polymerization reactors.

Polyolefin Products

[0275] The present disclosure also provides compositions of matter which can be produced by the processes described herein.

[0276] In at least one embodiment, a polyolefin is a propylene homopolymer, an ethylene homopolymer or an ethylene copolymer, such as propylene-ethylene and/or ethylene- alphaolefin (such as C4 to C20) copolymer (such as an ethylene-hexene copolymer or an ethylene-octene copolymer). A polyolefin can have an Mw/Mn of greater than 1 to 4 (such as greater than 1 to 3).

[0277] In at least one embodiment, a polyolefin is a homopolymer of ethylene or propylene or a copolymer of ethylene such as a copolymer of ethylene having from 0.1 to 25 wt% (such as from 0.5 to 20 wt%, such as from 1 to 15 wt%, such as from 5 to 17 wt%) of ethylene with the remainder balance being one or more C3 to C20 olefin comonomers (such as C3 to C12 alpha- olefin, such as propylene, butene, hexene, octene, decene, dodecene, such as propylene, butene, hexene, octene). A polyolefin can be a copolymer of propylene such as a copolymer of propylene having from 0.1 to 25 wt% (such as from 0.5 to 20 wt%, such as from 1 to 15 wt%, such as from 3 to 10 wt%) of propylene and from 99.9 to 75 wt% of one or more of C2 or C4 to C20 olefin comonomer (such as ethylene or C4 to C12 alpha-olefin, such as butene, hexene, octene, decene, dodecene, such as ethylene, butene, hexene, octene).

[0278] In at least one embodiment, a polyolefin, such as a polypropylene (e.g., iPP) or an ethylene-octene copolymer, has an Mw from 40,000 to 1,500,000, such as from 70,000 to 1,000,000, such as from 90,000 to 500,000, such as from 90,000 to 250,000, such as from 90,000 to 200,000, such as from 90,000 to 110,000.

[0279] In at least one embodiment, a polyolefin, such as a polypropylene (e.g., iPP) or an ethylene-octene copolymer, has an Mn from 5,000 to 1,000,000, such as from 20,000 to 160,000, such as from 30,000 to 70,000, such as from 40,000 to 70,000. In at least one embodiment, a polyolefin, such as a polypropylene (e.g., iPP) or an ethylene-octene copolymer, has an Mw/Mn value from 1 to 10, such as from 1.5 to 9, such as from 2 to 7, such as from 2 to 4, such as from 2.5 to 3, for example about 2.

[0280] In at least one embodiment, a polyolefin, such as a polypropylene (e.g., iPP) or an ethylene-octene copolymer, has a melt temperature (Tm) of from 100°C to 150°C, such as 110°C to 140°C, such as 120°C to 135°, such as 130°C to 135°C.

[0281] In at least one embodiment, a polymer of the present disclosure has a g’vis of greater than 0.9, such as greater than 0.92, such as greater than 0.95.

[0282] In at least one embodiment, the polymer is an ethylene copolymer, and the comonomer is octene, at a comonomer content of from 1 wt% to 18 wt% octene, such as from 5 wt% to 15 wt%, such as from 8 wt% to 13 wt%, such as from 9 wt% to 12 wt%.

[0283] In at least one embodiment, the polymer produced herein has a unimodal or multimodal molecular weight distribution as determined by Gel Permeation Chromatography (GPC). By“unimodal” is meant that the GPC trace has one peak or inflection point. By “multimodal” is meant that the GPC trace has at least two peaks or inflection points. An inflection point is that point where the second derivative of the curve changes in sign (e.g., from negative to positive or vice versus).

[0284] In at least one embodiment, the polymer produced herein has a composition distribution breadth index (CDBI) of 50% or more, such as 60% or more, such as 70 % or more. CDBI is a measure of the composition distribution of monomer within the polymer chains and is measured by the procedure described in PCT publication WO 93/03093, published February 18, 1993, specifically columns 7 and 8 as well as in Wild, L. et al. (1982)“Determination of Branching Distributions in Polyethylene and Ethylene Copolymers,” J. Poly. ScL, Poly. Phys. Ed, v.20, pp. 441-455 and US Patent No. 5,008,204, including that fractions having a weight average molecular weight (Mw) below 15,000 are ignored when determining CDBI.

[0285] Copolymer of the present disclosure can have a reversed comonomer index. The reversed-co-monomer index (RCI,m) is computed from ?;2 (mol% co-monomer C3, C4, Ce, Cx. etc.), as a function of molecular weight, where x2 is obtained from the following expression in which U is the number of carbon atoms in the comonomer (3 for C3, 4 for C4, 6 for Ce, etc.):

200 w2

x2 = _

-100 n- 2 w2 - n w2.

[0286] Then the molecular- weight distribution,

is modified to

I'T'Cz) by setting to 0 the points in that are less than 5% of the maximum of

; this is to effectively remove points for which the S/N in the composition signal is low. Also, points of W* for molecular weights below 2000 gm/mole are set to 0. Then M" is renormalized so that

and a modified weight-average molecular weight (.¾,/') is calculated over the effectively reduced range of molecular weights as follows:

The RCI,m is then computed as:

[0287] A reversed-co-monomer index (RCI,w) is also defined on the basis of the weight fraction co-monomer signal (wZ/tQQ) and is computed as follows:

[0288] Note that in the above definite integrals the limits of integration are the widest possible for the sake of generality; however, in reality the function is only integrated over a finite range for which data is acquired, considering the function in the rest of the non-acquired range to be 0. Also, by the manner in which

is obtained, it is possible that W^' is a discontinuous function, and the above integrations need to be done piecewise.

[0289] Three co-monomer distribution ratios are also defined on the basis of the % weight (w2) comonomer signal, denoted as CDR-l,w, CDR-2,w, and CDR-3,w, as follows:

where w2(Mw) is the % weight co-monomer signal corresponding to a molecular weight of Mw, w2(Mz) is the % weight co-monomer signal corresponding to a molecular weight of Mz, w2[(Mw+Mn)/2)] is the % weight co-monomer signal corresponding to a molecular weight of (Mw+Mn)/2, and w2[(Mz+Mw)/2] is the % weight co-monomer signal corresponding to a molecular weight of Mz+Mw/2, where Mw is the weight-average molecular weight, Mn is the number-average molecular weight, and Mz is the z-average molecular weight.

[0290] Accordingly, the co-monomer distribution ratios can be also defined utilizing the % mole co-monomer signal, CDR-l,m, CDR-2,m, CDR-3,m, as:

where x2(Mw) is the % mole co-monomer signal corresponding to a molecular weight of Mw, x2(Mz) is the % mole co-monomer signal corresponding to a molecular weight of Mz, x2[(Mw+Mn)/2)] is the % mole co-monomer signal corresponding to a molecular weight of (Mw+Mn)/2, and x2[(Mz+Mw)/2] is the % mole co-monomer signal corresponding to a molecular weight of Mz+Mw/2, where Mw is the weight-average molecular weight, Mn is the number-average molecular weight, and Mz is the z-average molecular weight.

[0291] In at least one embodiment of the present disclosure, the polymer produced by the processes described herein includes ethylene and one or more comonomers and the polymer has: 1) an RCI,m of 30 or more (alternatively from 30 to 250).

Blends

[0292] In another embodiment, the polymer (such as the polyethylene or polypropylene) produced herein is combined with one or more additional polymers prior to being formed into a film, molded part or other article. Other useful polymers include polyethylene, isotactic polypropylene, highly isotactic polypropylene, syndiotactic polypropylene, random copolymer of propylene and ethylene, and/or butene, and/or hexene, poly butene, ethylene vinyl acetate, low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE), ethylene vinyl acetate, ethylene methyl acrylate, copolymers of acrylic acid, polymethylmethacrylate or any other polymers polymerizable by a high-pressure free radical process, polyvinylchloride, polybutene-1, isotactic poly butene, ABS resins, ethylene- propylene rubber (EPR), vulcanized EPR, EPDM, block copolymer, styrenic block copolymers, polyamides, polycarbonates, PET resins, cross linked polyethylene, copolymers of ethylene and vinyl alcohol (EVOH), polymers of aromatic monomers such as polystyrene, poly-1 esters, polyacetal, polyvinylidine fluoride, polyethylene glycols, and/or polyisobutylene.

[0293] In at least one embodiment, the polymer (such as polyethylene or polypropylene) is present in the above blends, at from 10 to 99 wt%, based upon the weight of the polymers in the blend, such as 20 to 95 wt%, such as at least 30 to 90 wt%, such as at least 40 to 90 wt%, such as at least 50 to 90 wt%, such as at least 60 to 90 wt%, such as at least 70 to 90 wt%.

[0294] The blends described above may be produced by mixing the polymers of the present disclosure with one or more polymers (as described above), by connecting reactors together in series to make reactor blends or by using more than one catalyst in the same reactor to produce multiple species of polymer. The polymers can be mixed together prior to being put into the extruder or may be mixed in an extruder.

[0295] The blends may be formed using conventional equipment and methods, such as by dry blending the individual components and subsequently melt mixing in a mixer, or by mixing the components together directly in a mixer, such as, for example, a Banbury mixer, a Haake mixer, a Brabender internal mixer, or a single or twin-screw extruder, which may include a compounding extruder and a side-arm extruder used directly downstream of a polymerization process, which may include blending powders or pellets of the resins at the hopper of the film extruder. Additionally, additives may be included in the blend, in one or more components of the blend, and/or in a product formed from the blend, such as a film, as desired. Such additives are well known in the art, and can include, for example: fillers; antioxidants (e.g., hindered phenolics such as IRGANOX™ 1010 or IRGANOX™ 1076 available from Ciba-Geigy); phosphites (e.g., IRGAFOS™ 168 available from Ciba-Geigy); anti-cling additives; tackifiers, such as polybutenes, terpene resins, aliphatic and aromatic hydrocarbon resins, alkali metal and glycerol stearates, and hydrogenated rosins; UV stabilizers; heat stabilizers; anti-blocking agents; release agents; anti-static agents; pigments; colorants; dyes; waxes; silica; fillers; and talc.

Films

[0296] One or more of the foregoing polymers, such as the foregoing polyethylenes, polypropylenes, or blends thereof, may be used in a variety of end-use applications. Such applications include, for example, mono- or multi-layer blown, extruded, and/or shrink films. These films may be formed by any number of well-known extrusion or coextrusion techniques, such as a blown bubble film processing technique, wherein the composition can be extruded in a molten state through an annular die and then expanded to form a uni-axial or biaxial orientation melt prior to being cooled to form a tubular, blown film, which can then be axially slit and unfolded to form a flat film. Films may be subsequently unoriented, uniaxially oriented, or biaxially oriented to the same or different extents. One or more of the layers of the film may be oriented in the transverse and/or longitudinal directions to the same or different extents. The uniaxially orientation can be accomplished using typical cold drawing or hot drawing methods. Biaxial orientation can be accomplished using tenter frame equipment or a double bubble processes and may occur before or after the individual layers are brought together. For example, a polyethylene layer can be extrusion coated or laminated onto an oriented polypropylene layer or the polyethylene and polypropylene can be coextruded together into a film then oriented. Likewise, oriented polypropylene could be laminated to oriented polyethylene or oriented polyethylene could be coated onto polypropylene then optionally the combination could be oriented even further. Typically, the films are oriented in the Machine Direction (MD) at a ratio of up to 15, such as between 5 and 7, and in the Transverse Direction (TD) at a ratio of up to 15, such as 7 to 9. However, in at least one embodiment the film is oriented to the same extent in both the MD and TD directions.

[0297] The films may vary in thickness depending on the intended application; however, films of a thickness from 1 pm to 50 pm are usually suitable. Films intended for packaging are usually from 10pm to 50 pm thick. The thickness of the sealing layer is typically 0.2 pm to 50 pm. There may be a sealing layer on both the inner and outer surfaces of the film, or the sealing layer may be present on only the inner or the outer surface.

[0298] In at least one embodiment, one or more layers may be modified by corona treatment, electron beam irradiation, gamma irradiation, flame treatment, or microwave. In at least one embodiment, one or both of the surface layers is modified by corona treatment.

[0307] Solubility study of the activators: A saturated solution of the activator was prepared by slowly adding the solvent to a pre-weighed amount of the activator. The final volume was determined as the minimum amount of solvent required to convert the heterogenous mixture into a homogeneous solution. The concentration of the saturated solution is presented in millimoles of activator per liter of solution (mM). Alternatively, a mixture of the activator was prepared by adding the solvent to an excess amount of activator. The resulting heterogeneous mixture was separated from the undissolved solids by decanting the supemate mixture into a tared vial. Solvent was then added dropwise until the mixture became a homogeneous solution. The mass of the final solution was measured and then the solvent was evaporated to dryness to obtain the mass of the activator. The concentration of the saturated solution is presented in millimoles of activator per liter of solution (mM).

[0308] The solubility of the activators is summarized in Table 4. It was discovered that adding or increasing the length of aliphatic branches has a solubilizing effect on the activator, as these data show.

[0309] Polymerization-grade toluene and isohexane supplied by ExxonMobil Chemical Company were used as solvent after being purified by passing through a series of columns: two 500 cc Oxyclear cylinders in series from Labclear (Oakland, Calif.), followed by two 500 cc columns in series packed with dried 3 A mole sieves (8-12 mesh; Aldrich Chemical Company), and two 500 cc columns in series packed with dried 5 A mole sieves (8-12 mesh; Aldrich Chemical Company). 1-octene (C8) and 1-hexene (C6) (98%, Aldrich Chemical Company) were dried by stirring over NaK overnight followed by filtration through basic alumina (Aldrich Chemical Company, Brockman Basic 1).

[0310] Polymerization-grade ethylene (C2) was used and further purified by passing the gas through a series of columns: 500 cc Oxyclear cylinder from Labclear (Oakland, CA) followed by a 500 cc column packed with dried 3A mole sieves (8-12 mesh; Aldrich Chemical Company) and a 500 cc column packed with dried 5A mole sieves (8-12 mesh; Aldrich Chemical Company).

[0311] Polymerization grade propylene (C3) was used and further purified by passing it through a series of columns: 2250 cc Oxiclear cylinder from Labclear followed by a 2250 cc column packed with 3 A mole sieves (8-12 mesh; Aldrich Chemical Company), then two 500 cc columns in series packed with 5 A mole sieves (8-12 mesh; Aldrich Chemical Company), then a 500 cc column packed with Selexsorb CD (BASF), and finally a 500 cc column packed with Selexsorb COS (BASF). [0312] Solutions of the metal complexes and activators were prepared in a drybox using toluene or methylcyclohexane. Concentrations were typically 0.2 mmol/L. Tri-n- octylaluminum (TNOAL, neat, AkzoNobel) was typically used as a scavenger. Concentration of the TNOAL solution in toluene ranged from 0.5 to 2.0 mmol/L.

[0313] Polymerizations were carried out in a parallel pressure reactor, as generally described in US Pat Nos. 6,306,658; 6,455,316; 6,489,168; WO 00/09255; and Murphy, V. et al. (2003)“A Fully Integrated High-Throughput Screening Methodology for the Discovery of New Polyolefin Catalysts: Discovery of a New Class of High Temperature Single-Site Group (IV) Copolymerization Catalysts,” J. Am. Chem. Soc., v.125, pp. 4306-4317, each of which is fully incorporated herein by reference. The experiments were conducted in an inert atmosphere (N2) drybox using autoclaves equipped with an external heater for temperature control, glass inserts (internal volume of reactor = 23.5 mL for C2 and C2/C8; 22.5 mL for C3 runs), septum inlets, regulated supply of nitrogen, ethylene and propylene, and equipped with disposable PEEK mechanical stirrers (800 RPM). The autoclaves were prepared by purging with dry nitrogen at 110°C or 115°C for 5 hours and then at 25°C for 5 hours. Although the specific quantities, temperatures, solvents, reactants, reactant ratios, pressures, and other variables are frequently changed from one polymerization run to the next, the following describes a typical polymerization performed in a parallel pressure reactor.

[0314] Catalyst systems dissolved in solution were used in the polymerization examples below, unless specified otherwise.

[0315] Ethylene-Octene Copolymerization (EO). A pre-weighed glass vial insert, and disposable stirring paddle were fitted to each reaction vessel of the reactor, which contains 48 individual reaction vessels. The reactor was then closed and purged with ethylene. Each vessel was charged with enough solvent (typically isohexane) to bring the total reaction volume, including the subsequent additions, to the desired volume, typically 5 mL. 1-octene, if required, was injected into the reaction vessel and the reactor was heated to the set temperature and pressurized to the predetermined pressure of ethylene, while stirring at 800 rpm. The aluminum compound (such as tri-n-octylaluminum) in toluene was then injected as scavenger followed by addition of the activator solution (typically 1.0-1.2 molar equivalents).

[0316] The catalyst (and activator solutions for Run A) were all prepared in toluene. The catalyst solution (typically 0.020-0.080 pmol of metal complex) was injected into the reaction vessel and the polymerization was allowed to proceed until a pre-determined amount of ethylene (quench value typically 20 psi) had been used up by the reaction. Alternatively, the reaction may be allowed to proceed for a set amount of time (maximum reaction time typically 30 minutes). Ethylene was added continuously (through the use of computer controlled solenoid valves) to the autoclaves during polymerization to maintain reactor gauge pressure (P setpt, +/-2 psig) and the reactor temperature (T) was monitored and typically maintained within +/-1°C. The reaction was quenched by pressurizing the vessel with compressed air. After the reactor was vented and cooled, the glass vial insert containing the polymer product and solvent was removed from the pressure cell and the inert atmosphere glove box, and the volatile components were removed using a Genevac HT-12 centrifuge and Genevac VC3000D vacuum evaporator operating at elevated temperature and reduced pressure. The vial was then weighed to determine the yield of the polymer product. The resultant polymer was analyzed by Rapid GPC (see below) to determine the molecular weight, by FT-IR (see below) to determine percent octene incorporation, and by DSC (see below) to determine melting point (T_m).

[0317] Equivalence is determined based on the mole equivalents relative to the moles of the transition metal in the catalyst complex.

[0318] Polymer Characterization. Polymer sample solutions were prepared by dissolving polymer in 1, 2, 4-tri chlorobenzene (TCB, 99+% purity from Sigma- Aldrich) containing 2,6-di- tert-butyl-4-methylphenol (BHT, 99% from Aldrich) at 165°C in a shaker oven for approximately 3 hours. The typical concentration of polymer in solution was between 0.1 to 0.9 mg/mL with a BHT concentration of 1.25 mg BHT/mL of TCB.

[0319] To determine various molecular weight related values by GPC, high temperature size exclusion chromatography was performed using an automated "Rapid GPC" system as generally described in US Pat. Nos. 6,491,816; 6,491,823; 6,475,391; 6,461,515; 6,436,292; 6,406,632; 6,175,409; 6,454,947; 6,260,407; and 6,294,388; each of which is fully incorporated herein by reference. This apparatus has a series of three 30 cm x 7.5 mm linear columns, each containing PLgel 10 pm, Mix B. The GPC system was calibrated using polystyrene standards ranging from 580 to 3,390,000 g/mol. The system was operated at an eluent flow rate of 2.0 mL/minutes and an oven temperature of 165°C. 1 ,2, 4-tri chlorobenzene was used as the eluent. The polymer samples were dissolved in 1,2, 4-tri chlorobenzene at a concentration of 0.28 mg/mL and 400 uL of a polymer solution was injected into the system. The concentration of the polymer in the eluent was monitored using an evaporative light scattering detector. The molecular weights presented are relative to linear polystyrene standards and are uncorrected, unless indicated otherwise. [0320] Differential Scanning Calorimetry (DSC) measurements were performed on a TA-Q100 instrument to determine the melting point (T_m) of the polymers. Samples were pre-anneal ed at 220°C for 15 minutes and then allowed to cool to room temperature overnight. The samples were then heated to 220°C at a rate of 100°C/min and then cooled at a rate of 50°C/min. Melting points were collected during the heating period.

[0321] The weight percent of ethylene incorporated in polymers was determined by rapid FT-IR spectroscopy on a Bruker Equinox 55+ IR in reflection mode. Samples were prepared in a thin film format by evaporative deposition techniques. FT-IR methods were calibrated using a set of samples with a range of known wt% ethylene content. For ethylene- 1-octene copolymers, the wt% octene in the copolymer was determined via measurement of the methyl deformation band at -1375 cm ¹. The peak height of this band was normalized by the combination and overtone band at -4321 cm ¹, which corrects for path length differences.

[0322] Ethylene-octene copolymerization (EO). A series of ethylene-octene polymerizations were performed in the parallel pressure reactor according to the procedure described above. In these examples, rac-dimethylsilyl-bis(indenyl)hafnium dimethyl (MCN- 1) was used as the catalyst along with ammonium borate activators. In a typical experiment an automated syringe was used to introduce the following reagents into the reactor, if utilized, in the following order: isohexane (0.50 mL), 1-octene (100 pL), additional isohexane (0.50 mL), an isohexane solution of TNOAL scavenger (0.005 M, 100 pL), additional isohexane (0.50 mL), a toluene solution of the respective polymerization catalyst (110 pL, 0.2 mM), additional isohexane (0.50 mL), a toluene solution of the respective activator (110 pL, 0.2 mM), then additional isohexane so that the total solvent volume for each run was 5 mL. Catalyst and activator were used in a 1 : 1.1 ratio. Each reaction was performed at a specified temperature range between 50 and 120°C, typically 80°C, while applying about 75 psig of ethylene (monomer) gas. Each reaction was allowed to run for about 20 minutes (-1,200 seconds) or until approximately 20 psig of ethylene gas uptake was observed, at which point the reactions were quenched with air (-300 psig). When sufficient polymer yield was attained (e.g, at least -10 mg), the polyethylene product was analyzed by Rapid GPC, described below. Run conditions and data are reported in Table 5 where the general conditions were MCN-1 = 20 nmol; activator = 22 nmol; 1-octene = 100 pL; solvent = isohexane; total volume = 5 mL; tri(n- octyl)aluminum = 500 nmol; T = 80°C.

[0323] RUN B: Ethylene homopolymerization (PE). A series of ethylene polymerizations were performed in the parallel pressure reactor according to the procedure described above. In these examples, the same catalyst rac-dimethylsilyl-bis(indenyl)hafhium dimethyl (MCN-1) was used along with the indicated ammonium borate activators. In a typical experiment an automated syringe was used to introduce into the reactor the following reagents, if utilized, in the following order: isohexane (0.50 mL), an isohexane solution of TNOAL scavenger (0.005 M, 60 pL), additional isohexane (0.50 mL), a toluene solution of the respective polymerization catalyst (110 pL, 0.2 mM), additional isohexane (0.50 mL), a toluene solution of the respective activator (110 pL, 0.2 mM), then additional isohexane so that the total solvent volume for each run was 5 mL. Catalyst and activator were used in a 1 : 1.1 ratio. Each reaction was performed at a specified temperature range between 50 and 120°C, typically 80°C, while applying about 75 psig of ethylene (monomer) gas. Each reaction was allowed to run for about 20 minutes (-1,200 seconds) or until approximately 20 psig of ethylene gas uptake was observed, at which point the reactions were quenched with air (-300 psig). When sufficient polymer yield was attained (e.g., at least -10 mg), the polyethylene product was analyzed using the rapid GPC procedure described below. Run conditions and data are reported in Table 6 wherein the general conditions were: MCN-1 = 20 nmol; activator = 22 nmol; solvent = isohexane; total volume = 5 mL; tri(n-octyl)aluminum = 500 nmol; T = 80°C.

MBH-BF28 produced ethylene/octene copolymers of increased molecular weight (780-870 kg/mol) versus copolymers produced by the comparative NOMAH- BF28 (570-590 kg/mol). The percent incorporation of 1-octene was also increased from a range of 48-50 % from the polymer produced by NOMAH-BF28 to 61-65% produced by MBH-BF28. This resulted in a decrease in the peak melt temperature of the polymer from a range of 30-36°C to 26-31°C. Polymers produced by the activator/catalysts system with OdBH-BF28 showed similar trends, with increased molecular weight range of 770-800 kg/mol, 59-64% octene, and 26-27°C melting point.

[0325] The homo-polymerization of ethylene by the disclosed activator MBH-BF28 yielded polyethylene with increased molecular weight (1,000-1,400 kg/mol) compared to that produced by the comparative activator NOMAH-BF28 (820-1,000 kg/mol).
