摘要

综述了聚合物共混物相容性和相分离的研究现状。介绍了聚合物共混物的相容性理论、影响相容性的因素及改善相容性的方法和表征相容性的手段。聚合物共混物的相分离机理制约着材料的性能，旋节分离和成核-增长相分离分别形成不同的形态结构。旋节分离和成核-增长相分离所对应的动力学过程是不同的，散射光强与相分离时间分别满足指数和幂指数关系。

Abstract

Research progress of polymer blends are reviewedincluding compatibility and phase separation. The theory of polymer compatibilityinfluence factors on the compatibilitymethods of improving and evaluating the compatibility are elucidated. The phase separation mechanisms of polymer blends control the properties different morphology and sructure are formed according to the spinodal decomposition and nucleation and growth mechanism. The kinetic process for the two phase separation mechanism is obvious different. The scatter intensity is increased exponentially with the phase separation time for the spinodal decompositionhoweverit is power-law increase for the nucleation and growth phase separation.
