摘要： 以萘钾为引发剂,二甲基亚砜为溶剂制备了以烯丙基为末端基的聚环氧乙烷大单体,并利用末端双键的硅氢化反应合成了相对分子质量规整的聚环氧乙烷接枝聚硅氧烷的共聚物。产物经萃取精制后,用IR、1H NMR等方法进行了表征。

关键词: 聚环氧乙烷, 聚硅氧烷, 接枝共聚物, 大分子单体

Abstract: This work dealt with a new method for preparing graft copolymer composed of polysiloxane main chain and uniform polyoxyethylene grafts which were synthesized preliminarily through anionic polymerization using potassium naphthalene as initiator and dimethyl sulfoxide as solvent.The copolymer was characterized with IR and NMR and its expected molecular structure was verified.

Key words: graft copolymer, polysiloxane, polyoxyethylene, macromer
