摘要
从聚合反应的机理的角度,聚合反应分为逐步聚合和连锁聚合两类。连锁聚合按照引发"活性种"的差异又分为自由基聚合和离子聚合。离子聚合分为阳离子聚合、阴离子聚合和配位聚合。这些是所有《高分子化学》教材编排的重要线索。本文以自由基聚合、离子聚合、逐步聚合和配位聚合的机理为线索,进一步说明对《高分子化学》教材中关于聚合度公式的综合理解和融会,旨在提高学生对《高分子化学》重点内容和意义的认识和把握。
Polymerization reaction can be classfied to step-polymerization and chain-polymerization according to the polymerization mechanism. For difference of the active center, chain-polymerization is divided into free-radical polymerization and ion polymerization. Ion polymerization is including cationic polymerization, anionic polymerization and coordination complex polymerization. In this paper, equations of ＂polymerization degree ＂ （X^-n） in the course of polymer chemistry＂ have been discussed detailed baseed on the clue of different mechanisms of of free radical polymerization, ionic polymerization, coordination polymerization and step polymerization. It aims at to improve students understand of key points of the course ＂polymer chemistry＂ and of the sigenificence of these equations of the （X^-n）.
