摘要:A process of making a sulfonated telechelic polycarbonate is described. A dihydroxy compound, a carbonate ester, and an activated ester of a sulfobenzoic acid salt are reacted together. The method results in a sulfonated telechelic polycarbonate which has a high percentage of sulfonated end groups, is soluble, and is transparent.

摘要:A poly(arylene ether)-polysiloxane multiblock copolymer is prepared by the reaction of a hydroxy-diterminated poly(arylene ether), a hydroxyaryl-diterminated polysiloxane, and an aromatic diacid chloride. This synthesis overcomes disadvantages of known syntheses of poly(arylene ether)-polysiloxane block copolymers. The poly(arylene ether)-polysiloxane multiblock copolymer is useful for improving the melt processability of poly(arylene ether) compositions.

发明人：ZHOU TIANLEI; YAO HAIQING; MIYAUCHI MASAHIKO
权利人:KANEKA CORP
摘要:A crosslinkable thermoplastic resin composition may include a polymer formed from the reaction between a bis-benzoxazine monomer and a bifunctional comonomer having phenol, amine, and/or thiol functional groups, wherein the polymer contains at least one crosslinkable group. A method of forming a crosslinkable thermoplastic resin composition may include reacting a bis-benzoxazine monomer and a bifunctional comonomer to form a polymer containing at least one crosslinkable group. A method of forming a cured thermoplastic resin may include curing the crosslinkable thermoplastic resin composition by applying an external stimulus.

摘要:Thermally stable block copolyestercarbonates comprising chain members derived from at least one dihydroxy-substituted aromatic hydrocarbon moiety and at least one aromatic dicarboxylic acid moiety, said polymer being substantially free of anhydride linkages linking at least two mers of the polyester chain segments, are prepared by a method comprising the steps of: (a) preparing a hydroxy-terminated polyester intermediate comprising structural units derived from at least one dihydroxy-substituted aromatic hydrocarbon moiety and at least one aromatic dicarboxylic acid moiety; and (b) conducting a reaction of the polyester intermediate with phosgene in a reaction mixture comprising water, a substantially water-immiscible organic solvent, and a base, wherein base and phosgene are added simultaneously to the reaction mixture at a substantially constant molar ratio of base to phosgene for a time period of at least about 60% of the total amount of phosgene added.
