摘要:

在不同版本的《高分子化学》教材中,对于不可逆线形缩聚的聚酯化反应历程有两种不同的理解,这导致推导反应速率方程的过程存在一定差异。本文分析和对比了潘祖仁编写的《高分子化学》和乔治∙奥迪安(George Odian)编写的《Principles of Polymerization》两版中英文教材,阐述了造成速率方程推导过程存在差异的原因,以期为同行教学与学生学习提供参考。

Abstract:

Owing to the two different types of understanding on the kinetics of irreversible linear polycondensation, various deduction processes of reaction rate expressions exist in different "Polymer Chemistry" textbooks. In this paper, we elaborate the cause of the diversity in the reaction rate expressions derivation via analysis and comparison of a Chinese textbook and an English textbook, "Polymer Chemistry" written by Zuren Pan and "Principles of Polymerization" written by George Odian, respectively. We hope to provide a reference for teachers' teaching and students' learning.
