摘要

综述了基于链折叠概念的聚合物熔体结晶的方式理论，详述了结晶的三个方式并列举了文献提到的存在方式转变的体系，并对理论参数的获得和方式转变与形态变化的关系进行了讨论。

Abstract

The Regime theory is reviewed for melt crystallization of polymer with chain folding. In the theory

three regimes

referred to as Ⅰ

Ⅱ and Ⅲ

are defined according to the relationship of surface nucleation rate and surface spreading rate.Two kinetics methods used for detecting regime transition temperatures are mentioned:one is linear growth rate of lamella

the other is bulk overall crystallization rate.Polymer systems showing Ⅰ/Ⅱ or Ⅱ/Ⅲ transitions are listed and discussed.Some polymers exhibit both the two transitions in the same sample.This review also discusses the obtaining of theoretical parameters and the relationship between regime transition and morphology change.
