Heat-storage Behavior of PEG Segments in PET-PEG Copolymers
-
摘要: 采用重均分子量为１０００－４０００的聚乙二醇、对苯二甲酸二甲酯和乙二醇为原料合成了聚醚含量在４０－６０％（重量）的聚对苯二甲酸乙二酯－聚乙二醇共聚物，采用差热分析和宽角×射线衍射的方法，研究了共 聚物中聚乙二醇嵌段的储能行为，探讨了采用取醚嵌段可结晶的聚酯醚为原料熔融纺丝研制具有蓄热调温功能纤维的可能性。Abstract: The heat-storage behavior of PEG segments in PET-PEG copolymers was studied by DSC and WAXD, based on the synthesis of Poly(ethylene tereph-thalate) -Polyethyleneglycol copolymers which contains 40~60%wt. PEG using DMT, EG and PEG as raw materials. The pr
