摘　　要：研究了以茶皂素为起始剂,利用茶皂甙化学结构上的活性基团,在特定催化剂催化下与环氧丙烷进行开环聚合反应,制得一种全新的亲油性很好且具有茶皂甙表面活性的茶皂甙聚醚衍生物。讨论了各种反应条件对聚合反应的影响,同时研究了茶皂甙聚醚衍生物的表面活性。In this paper, the polymerization of theasaponins and propylene oxide with specific catalyst described. Via ring-opening polymerization, a new polyetherified derivative of theasaponins which has perfect lipophilicity was obtained. The surface activity of the polyethers was similar to that of theasaponins. Finally the influence of the technologic conditions such as temperature, pressure, and dosage of catalyst on polymerization rate were discussed. In addition the surface activity of the derivatives of theasaponins was discussed.
