摘要
综述了用于聚对苯二甲酸乙二醇酯（ＰＥＴ）、聚对苯二甲酸丁二醇酯（ＰＢＴ）化学扩链反应的羧基加成型和羟基加成型扩链剂，以及缩合型扩链反应、羧基加成型扩链反应和羟基加成型扩链反应、羧羟基同时加成型扩链反应。讨论了扩链反应、反应特性和扩链产物的性能，并简要介绍了国内研究概况。参考文献２０篇。
Addition type chain extension reactions with carboxyl and hydroxyl groups of poly(ethylene terphalate)(PET) and poly(butylene terephalate)(PBT) were reviewed,in addition to condensation type chain extension reaction,addition type chain extension reaction of hydroxyl or carboxyl or both of them.The chain extension reaction,reactivity and properties of extended polyester were discussed.At last,researching chain extension of polyester at domestic was outlined.
