摘要

不同于非晶态聚合物的模量-温度曲线中出现明显的“三态”和“两转变”

晶态高聚物的模量-温度曲线的宏观表现情况复杂。尽管部分高分子物理教材或习题中对此进行了讨论

但缺乏清晰的规律总结与图像描述。本文就晶态高聚物的模量-温度曲线进行分析

以期解答学生的疑惑

并实现更好的教学效果。

Abstract

Different from the apparent "three states" and "two transitions" in the modulus-temperature curve of amorphous polymers

the macroscopic performance of the modulus-temperature curve of crystalline polymers is more complicated. Though it is discussed in some polymer physics textbooks and exercises

there is a lack of clear rules and image descriptions. In this paper

the modulus-temperature curve of crystalline polymer is analyzed

in order to solve students' problems and achieve better teaching effect.
