摘要: 聚对苯二甲酸乙二醇醋(PET)-聚己内酯(PCL)是一种新的热塑弹性体。由于PET与PCL相容性较好,PET硬段含量可以在很宽的范围内变化,为全面研究热塑弹性体的结构与性能之间的关系提供了便利的条件。

Abstract: Molecular weight of PET-PCL segmented copolymer was measured by small angle scattering method. The value of dn/dc of hard segment was obtained on the basis of the additivity of dn/dc in block copolymers.
