【摘要】 聚醚酯弹性体是一类重要的热塑性弹性体,研究它的微相分离对提高其性能有重要的意义。笔者介绍了聚醚酯弹性体微相分离的热力学和动力学因素、微区形态与尺寸和微相分离程度的表征,讨论了聚酯硬段、聚醚软段以及加工方法对聚醚酯弹性体微相分离的影响。更多还原

【Abstract】 Poly(ether-ester) elastomers are a type of important thermoplastic elastomers, the study of microphase separation is very important to the promotion of their properties. The thermodynamics and dynamics factor, domain size, and characteristic methods of the poly(ether-ester) elastomers were elucidated. At the same time, the influences of the hard-segment,the soft-segment and processing methods on microphase separation were discussed.更多还原
