摘要

在双金属氰化物络合催化剂（DMC）作用下,茶皂甙与环氧丙烷开环聚合,在不破坏茶皂甙活性五元环的前提下,合成亲油性的茶皂甙聚醚衍生物。本文初步探讨了茶皂甙聚醚反应的机理,并用FTIR、NMR对聚醚进行了结构分析表征。结果表明,聚醚的序列结构以头-尾相连为主且呈无规立构分布的特点。

Abstract

The polymerization of theasaponins and propylene oxide catalyzed by double metal cyanide complex was described by the authors. Via ring-opening polymerization, a new polyetherified derivative of theasaponins which has perfect lipophilicity was obtained and the mechanism of polymerization was discussed. The structure of polyether was analyzed and characterized by FTIR and NMR. Results showed that head-tail addition and atactic structure were dominant in polyether microstructure.
