热塑性聚醚酯弹性体结晶行为的研究进展

Research progress in polyether ester thermoplastic elastomer

综述了热塑性聚醚酯弹性体(TPEE)的结晶相结构及其结晶行为的研究进展,详述了共聚因素对TPEE结晶行为的影响,包括硬段的含量、结构及结晶性,软段的含量、相对分子质量,第三组分的添加量等;介绍了研究TPEE相结构的手段及结晶行为的表征方法,主要为热容法、动态力学分析法及相互作用参数法。

The research progress in the crystalline phase structure and crystallization behavior of polyether ester thermoplastic e- lastomer （TPEE） was reviewed. The effect of copolymerization conditions on the crystallization behavior of TPEE was described in details, including the content, structure and crystallinity of hard segment, the content and relative molecular mass of soft seg- ment, the third component addition. The characterization of the phase structure and crystallization behavior was introduced for TPEE, dominantly including the heat capacity method, dynamic mechanical analysis and interaction parameter method.
