遥爪型液体聚合物及其多相共聚物的合成与表征——Ⅰ.端羧基乙烯基四氢呋喃-环氧丙烷液体共聚醚的合成
摘要:
本文探索了端羟基液体聚合物,四氢呋喃-环氧丙烷共聚醚,与顺丁烯二酸酐的酯化反应,得到了端羧基乙烯基液体聚合物。通过控制反应温度,配料比以及选择适宜的催化剂,使端基转化率达到了100%。用化学分析、核磁共振以及红外光谱分别对端基转化程度和聚合物结构进行了测定。

SYNTHESIS AND CHARACTERIZATION OF TELECHELIC LIQUID POLYMERS AND THEIR MULTIPHASE COPOLYMERS Ⅰ.Synthesis of Carboxyl-Vinylene-Terminated Tetrahydrofuranpropylene Oxide Liquid Copolymer
Abstract:
The esterifications of hydroxy——terminated liquid polymers, such as liquid tetrahydrofuran——propylene oxide copolymer,with maleic anhydride were investigated and carboxyl-vinylene-terminated liquid copolymers were obtained. Under certain conditions,such as reaction temperature,feed ratio and with suitable catalysts, 100% conversion of terminal groups has been achie-ved. The degree of terminal group conversion and the structure of the po-lymers were determined by chemical titration,IR and 1H-NMR, respecti-vely.
