摘　　要：热塑性聚酰胺弹性体(TPAE)是一种由聚酰胺为硬段和聚醚或聚酯等为软段构成的多嵌段共聚物,具有密度低、热稳定性好和耐磨性优等优异性能。TPAE的硬段和软段主要通过它们之间不同类型的端基反应连接,包括羧基与羟基、羧基与氨基、异氰酸酯基与羧基、酰氯与氨基、异氰酸酯基与氨基等官能团之间的缩合反应。本文综述了TPAE合成的研究进展,系统介绍了缩聚反应法、聚加成反应法、原位聚合反应法及其它合成TPAE的方法的反应机理与特点,并分析讨论了它们的优缺点。Thermoplastic polyamide elastomer(TPAE)is a kind of multiblock copolymer composed of polyamide as hard segment and polyether or polyester as soft segment.It has many excellent properties such as low density,good thermal stability and excellent wear resistance.The hard segment and soft segment of TPAE are mainly connected by different types of terminal groups,including the reaction between carboxyl group and hydroxyl group,carboxyl group and amino group,isocyanate group and carboxyl group,acyl chloride and amino group,isocyanate group and amino group.In this paper,the research progress about the synthesis methods of TPAE is reviewed.The mechanisms and characteristics of polycondensation,polyaddition,in-situ polymerization and other methods are systematically introduced,and their advantages and disadvantages are analyzed and discussed.
