Description

The load method and the aggregated application of the non-metallocene catalyst of composite carrier load

Technical field

The present invention is the preparation method of the non-metallocene olefin polymerization catalyst of composite carrier load, with and application in olefinic polymerization and copolymerization process, especially for the homopolymerization of ethene or the copolymerization of ethene and other alpha-olefin, belong to the load technology of catalyzer and the technical field of olefinic polymerization.

Background technology

Known homogeneous transition-metal catalyst has very high catalytic activity in olefinic polymerization, as unsupported Ziegler-Natta catalyst, metallocene calalyst for polymerization of olefine, constrained geometry olefin polymerization catalysis or non-metallocene olefin polymerization catalyst.Wherein, Ziegler-Natta catalyst is many active centre olefin polymerization catalysis, and then three kinds are single active center's olefin polymerization catalysis.Metallocene calalyst for polymerization of olefine, the constrained geometry olefin polymerization catalysis all contains cyclopentadienyl ligands in catalyst structure, and the non-metallocene olefin polymerization catalyst ligating atom is an oxygen, nitrogen, sulphur and carbon etc., do not contain cyclopentadienyl group, be to find at the initial stage nineties and obtain launching to study, its catalytic activity can meet or exceed metallocene calalyst for polymerization of olefine, and kept the polymkeric substance of metallocene catalysis system controlled simultaneously, narrow molecular weight distribution, can carry out molecule to polymkeric substance cuts out, the polymericular weight and the degree of branching such as can regulate and control at advantage, and because a little less than this type of catalyzer oxytropism, can realize the copolymerization of polar monomer and alkene, thereby produce the functional polyolefin material of excellent performance.

During polymerization in homogeneous phase, the phenomenon that the polymkeric substance of formation can produce sticking still and twine stirring rake, this heat exchange to material in the normal operation of reactor and the reactor has bigger influence, is unfavorable for industrialized continuous production.In addition, need a large amount of promotor methylaluminoxane in the homogeneous catalysis system, polyolefinic production cost is increased, and because the introducing of a large amount of promotors, product performance have also been produced adverse influence, some in addition need in postorder processing, remove the aluminium of introducing in the polymerization process, further increased the cost of process.A kind of olefinic polymerization that patent WO03/010207 is prepared and copolymerization catalyst or catalyst system, have olefinic polymerization widely and copolymerization performance, be applicable to the polymerization technique of various ways, but when olefinic polymerization, need higher promotor consumption could obtain suitable olefin polymerizating activity, and polymerization process exist sticking still phenomenon.

Experience (Chem Rev, 2000,100:1347 according to the metallocene calalyst for polymerization of olefine industrial applications; Chem Rev, 2000,100:1377), the loadization of homogeneous phase non-metallocene olefin polymerization catalyst is very necessary.

The main purpose of catalyst cupportization is the granulating form for polymerization that improves catalyzer and polymkeric substance.It shows as the initial activity that has suitably reduced catalyzer to a certain extent, thereby reduces even avoided caking or the poly-cruelly phenomenon in the polymerization process; Catalyzer can improve the form of polymkeric substance after loadization, improve the apparent density of polymkeric substance, can make it satisfy more polymerization technique process, as vapour phase polymerization or slurry polymerization etc., the process of load simultaneously can reduce Preparation of catalysts and olefinic polymerization cost significantly, improve polymerization, prolong polymerization catalyst active lifetime etc.EP 0206794 use MAO is oxide support modified and use metallocenes subsequently, has objectively limited the controllability of the performance of solid support material to the polymer particles granularity.EP685494 acts on hydrophilic oxide with methylaluminoxane, with polyfunctionality organic crosslinking agent and the MAO/ of use activation subsequently metallocene complex, might reduce the tap density of polymerisate, is unfavorable for the industry use.

Patent CN1352654 selects for use organoaluminum, organosilicon, organic-magnesium and organoboron compound to handle carrier, single site olefin polymerization catalysts of load heteroatom ligand then, and resulting loaded catalyst has high reactivity and long storage life.EP 295312 has described under the situation that the organic or inorganic bead-type substrate exists, and aluminoxanes solution is contacted with a kind of solvent that can not dissolve aikyiaiurnirsoxan beta, causes aikyiaiurnirsoxan beta to be deposited on the carrier.WO97/26285 describes the method for preparing carried metallocene catalyst under the high pressure, and the production cycle is long, and load efficiency is not high.And CN1307065 handles carrier back loading metallocene catalyst with alkylaluminoxane under the ultra-sonic oscillation effect, and the load process is also uneconomical.

In order to improve the bonding strength between carrier and the catalyzer, CN1162601 adopts the difunctionality linking agent to continue to handle the carrier of process aikyiaiurnirsoxan beta or alkylaluminium cpd processing.Patent CN1174849 handles the silicon-dioxide of dehydroxylation in the toluene medium with MAO after, load metallocene catalyst does not more provide the polymerization activity data of loaded catalyst in the literary composition.Patent CN1120550 proposes a kind of method of catalyst cupportization, it is mainly with hydrophilic, macropore, inorganic carrier in small, broken bits, react with aikyiaiurnirsoxan beta after elder generation's thermal activation, then with multifunctional organic crosslinking agent reaction, mix with the reaction product of metallocenes and activator at last, thereby make carried type metallocene catalyst, but the consumption of aikyiaiurnirsoxan beta is higher in loading process.CN 1053673 adopts microwave action that catalyzer and the promotor that loads on the solid support material are contacted with each other in suspension, and then makes a kind of loaded catalyst of rock steady structure, but this method needs microwave device, and it is also remarkable to operate.CN1323319 adopts catalystic material to flood the porous particle carrier of mechanical flow state, the catalyst solution that is about to be equivalent to pore volume is sprayed onto on the carrier, and then drying makes loaded catalyst, this load method objectively requires the solubleness of catalyzer enough big, otherwise can not guarantee the homogeneity and the charge capacity of catalyst cupport.Patent WO96/00243 has described a kind of preparation method of supported catalyst compositions, be included in the two indenyl metallocenes and the aikyiaiurnirsoxan beta of mixing bridging in the solvent and form solution, described solution is combined with porous support, and the cumulative volume of wherein said solution is lower than the liquor capacity when forming slurries.

The catalyzer that with the Magnesium Chloride Anhydrous is carrier demonstrates advantages of high catalytic activity in olefin polymerization process, but this type of catalyzer is highly brittle, and is broken easily in polymerization reactor, thereby causes polymer morphology bad.Silicon dioxide carried catalyzer has good flowability, can be used for gas fluidised bed polymerisation, but silicon dioxide carried metallocene and non cyclopentadienyl catalyst then show lower catalytic activity.Therefore, just may prepare and have high catalytic activity, the catalyzer of the controlled and good abrasion strength resistance of globule size if magnesium chloride and silicon-dioxide are well organically combined.

People such as K.Soga are at J.Polym.Sci., Polym.Chem.Ed.35, the polymerization that the cyclopentadiene titanous chloride is carried on the catalyzer that makes on the magnesium chloride support discussed in 291～311 articles of delivering, this catalyzer and triisobutyl aluminum cocatalyst are used and can prepare polypropylene, and have high polymerization activity.

EP 0878484 has reported the MgCl with low content of magnesium chloride (less than 3%) ₂/ SiO ₂The catalyzer of two carrier loaded zirconium metallocene-prepared can be used for the homopolymerization or the copolymerization of ethene, has catalytic activity preferably.

Patent CN 1364817 discloses magnesium chloride/silicon dioxide carried beta-diketon half metallocene-titanium metal Preparation of catalysts method and aggregated application, and its ethylene polymerization activity reaches 7.42 * 10 ⁶Gram polyethylene/mole titanium hour, but in the patent less than concrete data about polymkeric substance granulating aspect of performance.
