Description
Cross Reference to Related Applications
The present application claims priority from U.S. provisional patent application No. 63/293106 filed on 12 months 23 and european patent application No. 22161495.1 filed on 3 months 11 of 2022, the entire contents of which are incorporated herein by reference for all purposes.
Technical Field
The present disclosure relates to a side chain functionalized copolymer (P1) and a method for preparing the side chain functionalized copolymer (P1). The invention also relates to the use of the copolymer (P1) for producing functional films (i.e. hydrophobic, hydrophilic, biomarker fluorescent tagged films), the use of the copolymer (P1) in composite materials, 3D printing applications, and the use of the copolymer (P1) in functional coatings.
Background
Poly (aryl ether sulfone) (PAES) polymers belong to the group of high performance thermoplastics and are characterized by high heat distortion resistance, good mechanical properties, excellent hydrolysis resistance, and inherent flame retardancy. General and useful PAES polymers have many applications in electronics, electrical industry, medicine, general engineering, food processing, and 3D printing. PAES polymers can be used in injection molded articles, composites and membranes (e.g., for water purification or hemodialysis).
PAES are typically made by polycondensation reactions using dihalodiphenylsulfones (sulfone monomers) and at least one aromatic diol monomer such as bisphenol a ("BPA"), biphenol ("BP"), or dihydroxydiphenyl sulfone (DHDPS) (also known as bisphenol S ("BPs")).
A commercially important group of PAES comprises polysulfone polymers, herein referred to as polysulfones, PSUs for short. PSU polymers contain repeat units derived from the condensation of BPA and dihalogen sulfone monomers, such as 4,4' -dichlorodiphenyl sulfone (DCDPS). Such PSU polymers are sold under the trademark Solvi specialty Polymer Co., ltd (Solvay Specialty Polymers USA, LLC)Are commercially available. The Tg of PSU is typically 185 ℃. The structure of the repeat unit of such PSU polymers is shown below:
another important group of PAES includes polyethersulfone polymers, abbreviated PES. PES polymers are derived from the condensation of BPS and dihalogen sulfone monomers (e.g., DCDPS). Such PES polymers are commercially available from Solvin specialty polymers, inc. of USA Are commercially available. The Tg of PES is typically 220 ℃. The structure of the repeating unit of such PES polymer is as follows:
another important group of PAES includes poly (biphenyl ether sulfone) polymers, abbreviated PPSU. PPSU is made by reacting 4,4' -Biphenol (BP) and a dihalosulfone monomer (e.g., DCDPS), and is notable for its trade name from the american sorv specialty polymer company, inc Are commercially available. The Tg of PPSU is typically 220 ℃. The structure of the repeat unit of such PPSU polymer is shown below:
while PAES polymers have many advantages and good physical properties, it is sometimes desirable to tailor these properties to improve performance in specific applications. For example, in membrane filtration, it is sometimes desirable to increase the hydrophilicity of PAES to improve key membrane performance attributes, such as flow rate. Modification of the basic properties, including but not limited to hydrophilicity, is often achieved by combining two homopolymers to prepare block copolymers having a combination of the inherent properties of each individual homopolymer. For example, in membrane applications, PAES homopolymers may be covalently linked to hydrophilic homopolymers to synthesize new PAES-hydrophilic block copolymers that have superior membrane properties due to enhanced flow induced by the hydrophilic component, while retaining the mechanically robust and amorphous pore structure of the PAES component.
The present invention provides a side chain functionalized copolymer and a process for preparing such a copolymer. These functionalized copolymers are complex polymer structures that can be used in potentially diverse applications, such as for the preparation of films, composites and coatings.
Disclosure of Invention
One aspect of the present disclosure relates to a side chain functionalized poly (aryl ether sulfone) (PAES) copolymer (P1) as defined in claim 1. The copolymer (P1) comprises poly (aryl ether sulfone) (PAES) repeat units (R P1), and PAES repeat units having pendant groups (R x P1), more precisely PAES repeat units functionalized with pendant groups (R x P1).
The repeating unit (R P1) contains thioether functionalities which have several advantages. It is a stable but at the same time multifunctional functional group that can be easily modified to fine tune the properties of the PAES copolymer (P1).
The glass transition temperature Tg of the copolymer (P1) is equal to or greater than the Tg h of a homopolymer consisting essentially of identical repeating units (R P1), preferably measured by Differential Scanning Calorimetry (DSC) according to ASTM D3418. The copolymer (P1) preferably has a Tg > Tg h, more preferably a Tg of > 5 ℃ plus Tg h, yet more preferably a Tg of > 7 ℃ plus Tg h, yet even more preferably a Tg of > 10 ℃ plus Tg h.
The invention also relates to a process for preparing the copolymer (P1) from the copolymer (P0) comprising allyl groups and/or functional groups containing carbon-carbon double bonds which are reactive and can therefore be used to effectively modify the copolymer. Thus, the present invention provides a method of introducing functionality into PAES polymers, and the resulting copolymers can then be further used in various applications, such as for preparing films.
The invention also relates to the use of the copolymer (P1) for producing films, composite materials or coatings.

The functional groups of the copolymer (P1) are internal functionalization within the copolymer backbone. Internal functionalization results from a stepwise polymerization in the presence of allyl-substituted monomers, which advantageously gives the system versatility since the content of functionality can be adjusted by varying the content of allyl-substituted monomers in the reaction mixture. The allyl-substituted monomer comprises two pendant allyl side chains, each side chain comprising 3 to 7 carbon atoms according to the invention.
The copolymer (P1) of the present invention comprises:
-a repeating unit (R P1) having formula (M):

Wherein the method comprises the steps of

The copolymer (P1) of the present invention is in the form of a racemate product. Due to the presence of base and the high temperature during polymerization, allylic substituted monomers are typically racemized during polymerization in such a way that the position of the double bond may vary along the side chain. This results in the formation of molecules that differ from each other in that the double bond may be at the end of the side chain or at one carbon before the end of the side chain. The amount of racemization depends on the reaction time and temperature.
In some embodiments, copolymer (P1) is such that in the repeating unit (R P1), T is selected from the group consisting of a bond, -SO 2-、-C(CH3)2 -, and mixtures thereof.

In some embodiments, copolymer (P1) is such that R 2 in the repeating unit (R P1) is independently selected from the group consisting of:
-CH2-COOH,
-(CH2)2-OH,
-(CH2)2-NH2,
-(CH2)3-SO3Na,
-(CH2)3-Si(OCH3)3,
-(CH2)2-(CF2)7-CF3,
-CHO,
- (CH 2)9-CH3, and
-CH 2 -Ph, wherein Ph is benzene.
In some embodiments, copolymer (P1) comprises at least 50mol.% total of repeating units (R P1) and (R x P1) based on the total moles in copolymer (P1). The copolymer (P1) may for example comprise at least 60mol.%, at least 70mol.%, at least 80mol.%, at least 90mol.%, at least 95mol.%, at least 99mol.% of recurring units (R P1) and (R x P1) in total based on the total moles of the copolymer (P1). The copolymer (P1) may preferably consist essentially of recurring units (R P1) and (R x P1).

When PAES repeat unit (R P1) has formula (M1) and the corresponding homopolymer is PSU having Tg h of about 185 ℃, PAES copolymer (P1) comprising the same PAES repeat unit (R P1) having formula (M1) and functionalized repeat unit (R P1) having formula (N) (wherein in formulae (G N1) to (G N6) W is a bond or-SO 2 -, preferably-SO 2 -) Tg > Tg PSU, preferably Tg > 3 ℃ + Tg PSU, more preferably Tg > 5 ℃ + Tg PSU, still more preferably Tg > 7 ℃ + Tg PSU, yet even more preferably Tg > 10 ℃ + Tg PSU.

This is in contrast to what is described for the functionalized PAES copolymers in WO 2020/187684 A1 and WO 2021/123405 A1, in which cysteamine is used during the synthesis, wherein the copolymers described in the examples have a glass transition temperature Tg which is less than the Tg of their corresponding homopolymers. The functionalized PSU copolymer (P1-C) of WO'684 prepared with cysteamine hydrochloride had a Tg of 175 ℃ (< Tg PSU). The functionalized PSU copolymers (P1-A), (P1-B) and (P1-E) of WO'405 have Tg (< Tg PSU) at 150 ℃, 143 ℃ and 162 ℃. These functionalized PSU polymers were prepared from copolymer precursors made using DCDPS, diallyl bisphenol a, and bisphenol a. The functionalized PPSU copolymer (P1-C) of WO '405 has a Tg (< Tg PPSU) of 170 ℃ and the functionalized PPSU copolymer (P1-C) is prepared from a copolymerization precursor made using DCDPS, diallyl bisphenol a and 4,4' -biphenol. The functionalized PES copolymer of WO'405 (P1-D) has a Tg of 190 ℃ (< Tg PES) and is prepared from copolymer precursors made using DCDPS, diallyl bisphenol a and bisphenol S.
The copolymer (P1) of the present invention may have a glass transition temperature Tg ranging from 170℃to 240℃or 185℃to 240℃and preferably from 190℃to 240℃and more preferably from 195℃to 240℃or from 200℃to 235 ℃.
The glass transition temperature is preferably measured according to ASTM D3418, preferably by Differential Scanning Calorimetry (DSC). For example, DSC measurements can be performed using Q100 from TA instruments (TA instruments) and under a nitrogen purge. The DSC profile was recorded by heating, cooling, reheating and then cooling the sample between 25 ℃ and 320 ℃ at a heating and cooling rate of 20 ℃/min. The second heating curve was used to provide reported Tg values unless indicated otherwise.
The thioether bond-S-R 2 contained in the repeating unit (R P1) has several advantages. First, the thioether linkage is a stable, non-hydrolyzable linkage, which is important for applications in membranes, especially for medical applications. Moreover, the thioether bond is a highly biocompatible and biostable bond, and thus can be used in hemodialysis applications; many bioactive molecules contain thioether moieties, such as biotin. However, after treatment with a suitable oxidizing agent (like hydrogen peroxide), this bond can be oxidized to form a sulfoxide and sulfone linkage. In addition, the thioether can be easily alkylated with an alkyl halide to form a sulfonium salt; the polymeric sulfonium salt can then be used in chemical conversions, such as epoxidation. In addition, thioethers can coordinate or bind to heavy metals, and thus the copolymers of the present invention can be used as polymeric ligands for metal removal.
The copolymers (P1) according to the invention can also be characterized by their end groups. The polymer end groups are part of the respective ends of the PAES copolymer (P1) chain.
Depending on the monomers used to prepare the copolymer (P0), from which the copolymer (P1) is prepared, and the additional end-capping agent possibly used during the polycondensation process, or the protonating agent possibly added after polymerization (in order to obtain phenolic-OH end groups), the copolymer (P1) may, for example, have end groups derived from the monomers and/or end groups derived from the end-capping agent. Since the copolymers (P0) are generally produced by polycondensation between at least two dihydroxy components and dihalogenated components and without end-capping agents, the end groups of the copolymers (P1) generally comprise, or preferably consist of, hydroxy end groups and halogenated end groups, such as chlorinated end groups. The production of the copolymer (P0) from which the copolymer (P1) is derived preferably excludes the use of aminophenols as end-capping agents, which at least partially convert some of the halogenated end groups into amine end groups.

The temperature of the reaction mixture used to prepare copolymer (P0) is maintained at about 150℃to about 350℃and preferably about 210℃to about 300℃for about 1 hour to 15 hours.

The solution may then be used as such in the process of the invention to react the copolymer (P0) with the compounds R 2 -SH, or alternatively the copolymer (P0) may be recovered from the solvent, for example by coagulation or devolatilization of the solvent.
