摘要:

高分子化学缩聚反应教学中有几个比较容易困扰学生的问题,如基团数比(r)值的含义、聚酯化线形平衡缩聚动力学方程的推导与应用等,本文结合多年的教学实践经验,对这些问题进行了探讨和梳理,可为同行教学和学生学习提供一定的参考。

关键词: 缩聚反应, 基团数比r, 聚酯化线形平衡缩聚动力学方程

Abstract:

There are some problems in the condensation polymerization teaching, such as the ratio of function groups, the Polyester linear equilibrium polycondensation kinetic equation, etc. The students were often puzzled with these problems. Based on many years of polymer chemistry teaching experience, these problems were discussed in this paper to provide some reference for peers teaching and students learning.

Key words: Condensation polymerization, The ratio of function groups, The polyester linear equilibrium polycondensation kinetic equation
