The structure and property of polybutylene terephtha late (PBT) -polyethylene glycol(PEG) block copolymer fiber synthesed from polyesters and polyethers have been studied by DSC, WAXD, SAXS as well as dynamic mechenical and thermo-gravimetric methods.

• 本文讨论了由聚对苯二甲酸丁二酯与聚乙二醇熔融缩聚合成PBT-PEG嵌段共聚酯的新方法。 用DSC、WAXD、SAXS、动态力学和热重分析的方法对共聚酯纤维的结构与性能进行了研究。
