摘要/Abstract

摘要： 采用熔融缩聚法设计合成了对苯二甲酸聚乙二醇酯对苯二甲酸丁二醇酯共聚物(PEGT/PBT),并用GPC、FTIR、NMR对合成产物进行了表征,结果表明所得共聚物与设计相符合。

Abstract: Polyether-ester thermoplastic elastomer, such as polyethylene glycol terephthalate-butylene terephthalate copolymer (PEGT/PBT) was synthesized by melt polycondensation from polyethylene glycol, butanediol and dimethyl terephthalate with Ti(OBu) 4 as catalyst. The copolymer was characterized by means of GPC?FTIR? 1HNMR and 13 CNMR. The results show that the product consists with what we have designed.

Key words: PEGT/PBT copolymer, thermoplastic elastomer, poly(ether-ester) segmented copolymers
