摘　　要：介绍了环氧类单体阳离子开环聚合的反应机理,活性单体机理与活性链端机理相结合可解释反应过程中环状齐聚物的生成过程。归纳了合成端羟基聚环氧氯丙烷的各种催化体系,并对产物的后处理方法进行了总结。The reaction mechanism for the cationic ring-opening polymerization of epoxy-type monomers is introduced. The formation course of cyclic oligomers in the reaction can be explained by combining the active monomer mechanism and active chain end mechanism. The various catalytic systems for synthesizing hydroxyl- terminated polyepichlorohydrin are summed up, and the post-treatment methods for the product are summarized.
