摘要

本文基于高聚物在物理老化和拉伸变形过程中构象弛豫行为的实验结果

进一步阐明了高分子链局部凝聚缠结的观点。

Abstract

A new chain entanglement viewpoint of polymer

that is the local inter - chain cohesion in the glassy state as a kind of cohesional chain entanglement

was used to explain the mechanism of the endothermic peak of aged polymers in DSC measurement and stress yielding in uniaxial stretching process.
