  Compositions containing polyphenylene ether-poly(alkylene dicarboxylate) copolymers are prepared by a reaction between the two polymers and, optionally, at least one functionalizing agent therefor. The functionalizing agent may first be reacted with the polyphenylene ether and the resulting functionalized polyphenylene ether in turn reacted with a functionalized or unfunctionalized poly(alkylene dicarboxylate). Alternatively, an unfunctionalized or hydroxyalkyl-functionalized polyphenylene ether may be incorporated in a conventional polyester-forming reaction. The copolymer-containing compositions are characterized by a number of desirable properties including high impact strength and solvent resistance.

  含有聚苯醚-聚(亚烷基二甲酸酯)共聚物的组合物是通过两种聚合物和至少一种官能化剂的反应制备的。官能化剂可首先与聚苯醚反应，然后将得到的官能化聚苯醚与官能化或未官能化的聚(烷烃二羧酸盐)反应。或者，也可以将未官能化或羟烷基官能化的聚苯醚加入到传统的聚酯形成反应中。含共聚物的组合物具有许多理想的特性，包括高冲击强度和耐溶剂性。

  The present invention provides an aromatic polyester which is substantially free from the occurrence of coloration and retains significantly high transparency even after being thermally processed at high temperature and which has high flowability. The aromatic polyester contains a polyhydric phenol residue and a residue of any one of aromatic polycarboxylic acid, halide thereof, and anhydride thereof, and terminals of the aromatic polyester have a structure represented by the formula -C(O)-R. The aromatic polyester has an end-capping rate of 90% or higher and a weight average molecular weight (Mw) ranging from 3,000 to 1,000,000.

  本发明提供了一种芳香族聚酯，该聚酯基本上不会发生着色，即使在高温热加工后仍能保持明显的高透明度，并且具有高流动性。芳香族聚酯含有多羟基苯酚残留物和芳香族多羧酸、其卤化物和其酸酐中任意一种的残留物，芳香族聚酯的端基具有式 -C(O)-R 所代表的结构。芳香族聚酯的端盖率为 90% 或更高，重量平均分子量（Mw）为 3,000 至 1,000,000 之间。

  (EN) Compositions containing polyphenylene ether-poly(alkylene dicarboxylate) copolymers are prepared by a reaction between the two polymers and, optionally, at least one functionalizing agent therefor. The functionalizing agent may first be reacted with the polyphenylene ether and the resulting functionalized polyphenylene ether in turn reacted with a functionalized or unfunctionalized poly(alkylene dicarboxylate). Alternatively, an unfunctionalized or hydroxyalkyl-functionalized polyphenylene ether may be incorporated in a conventional polyester-forming reaction. The copolymer-containing compositions are characterized by a number of desirable properties including high impact strength and solvent resistance.(FR) Des compositions contenant des copolymères d'éther de polyphénylène-poly-(alkylène dicarboxylate) sont préparées par une réaction entre les deux polymères et, éventuellement, au moins un agent de fonctionnalisation pour ceux-ci. L'agent de fonctionnalisation peut d'abord réagir avec l'éther de polyphénylène et l'éther de polyphénylène fonctionnalisé obtenu réagit à son tour avec un poly(alkylène dicarboxylate) fonctionnalisé ou non fonctionnalisé. Dans une variante, un éther de polyphénylène non fonctionnalisé ou à fonction hydroxyalkyle peut être incorporé dans une réaction conventionnelle de formation de polyester. Les compositions contenant les copolymères sont caractérisées par un nombre de propriétés désirables dans lesquelles sont incluses une résistance élevée aux impacts et une forte résistance aux solvants.
