摘　　要：聚环氧氯丙烷具有独特的性能,包括低温柔性、耐热性和耐油性,是广泛应用的一类高端聚醚产品。但是聚环氧氯丙烷由于单体活性低,合成非常困难,成为目前制约其发展的壁垒。本文回顾了环氧氯丙烷聚合方法的发展历程,重点介绍了Vandenberg催化剂、阳离子开环聚合、双金属氰化物催化剂、单体活化阴离子开环聚合等聚合方法,并对每种聚合方法对聚合物结构和分子量的影响进行了详细讨论。我们还对目前工业上环氧氯丙烷聚合物的发展进行了总结和展望。Due to its unique properties, including low-temperature flexibility, heat resistance and oil resistance, polyepichlorohydrin is a kind of high-end polyether products widely used. However, due to the low monomer activity, the synthesis of polyepichlorohydrin is very difficult, which has become a barrier restricting its development. The development of epichlorohydrin polymerization methods was reviewed, with emphasis on Vandenberg catalyst, cationic ring opening polymerization, double metal cyanide catalyst, monomer activated anionic ring opening polymerization and other polymerization methods, and the effects of each polymerization method on polymer structure and molecular weight were discussed in detail. The development of epichlorohydrin polymer in industry was also summarized and prospected.
