摘要

开环聚合反应是高分子化学中的一类重要反应

但因开环聚合过程既涉及到了逐步聚合和连锁聚合的特点

又涉及到了阴离子聚合和阳离子聚合的基本方式

因此开环聚合反应一直都是《高分子化学》课堂教学的难点。笔者从课堂实际角度出发

结合开环聚合的基本概念和特征总结出一套口诀用于《高分子化学》中开环聚合反应章节教学

并详细解释了口诀中所归纳的知识点。希望用口诀教学的模式深入浅出地教授开环聚合章节

克服开环聚合教学过程中的难点。

Abstract

Ring-opening polymerization is one of important chemical reactions in chemical industry

and also is very hard section in the polymer chemistry course due to it contains many features such as chain polymerization

stepwise polymerization

and cationic (or anionic) polymerization. The authors developed a series of pithy formula about ringopening polymerization to guide the teaching course based on the features of ring-opening polymerization reaction during the practical teaching process. Moreover

the detailed illustrations could be expressed by this manuscript. The authors hope this kind of pithy formula can provide helps to teachers and students

and decrease the teaching difficulties of ring-opening polymerization section. This manuscript can help students clearly understand the mechanisms and kinetics in ring-opening polymerization.
