中文摘要：

高分子的微观晶体生长动力学理论是高分子科学的重要研究课题之一。本文系统地介绍了近年来发展起来的高分子晶体生长动力学模型—链内成核模型。该模型能够对高分子结晶过程中的链折叠现象、分子分凝现象、二元链长共结晶现象、Regime转变现象和半晶织构现象给出较为合理的解释。这些现象为高分子结晶所特有,揭示了高分子有序化相转变行为的特殊性。在结语部分,本文还对比描述了以链间成核模式为主的一些情景,并对链内成核模型的进一步发展做了展望。

英文摘要：

Polymer crystal theory is one of the most important problems in polymer science. In this paper,we introduced the intramolecular nucleation model for polymer crystallization.By this model,we can explain the phenomena of chain folding,molecular segregation,regime transitions,cocrystallization of binary mixture of different chain lengths,and the semi-crystalline texture.These phenomena are unique for polymer crystallization,revealing the specific behaviors of ordering phase transitions of polymers.In the end,w...
