在“高聚物的结构与性能”课程中讲透高聚物的特点

Laying Stress on the Characteristics of Polymers when Teaching Course of "The Structure and Properties of Polymers

通过对高分子链的柔性、聚合物独有的熵弹性、显著的粘弹性、特有的描述链段运动的WLF方程、可能实现的大尺寸取向和小尺寸解取向、银纹、单链凝聚态、折叠链片晶和伸直链晶体、分子量的多分散性、高分子溶液特性和高聚物熔体的弹性行为等的讨论 ,希望能突出“高聚物的结构与性能”课程中高聚物的特点。

When teaching course of \!The Structure and properties of Polymers\', it is important to lay stress on the characteristics of polymers. The paper presents much discussion on characteristics of polymers, such as flexibility of macromolecular chain, unique entropy elasticity and notable viscoelasticity of polymer materials, peculiar WLF equation, possible orientation of large scale motion unit and dis\|orientation of small scale motion unit, crazing, single\|chain condensed state, folded lamellar crystals and macroscopic single polymer crystals with stretched chain, multi\|distribution of molecular weight, properties of polymer solution and elasticity of polymer melts.
