| 摘 要： | 缩聚和逐步聚合反应是高分子化学教学和学习中的重要内容。本文讨论了缩聚和逐步聚合的关系;线型缩聚反应动力学和线型缩聚缩聚物数均聚合度的计算。线型缩聚反应动力学表达式的推导过程有助于学生初步掌握聚合动力学的一般处理方法;控制线型缩聚物聚合度的手段可以分为三种,通过对这三种情况下线型缩聚聚合度表达式的推导,使学生进一步明确聚合机理及控制聚合度的方法。

| Abstract: | Polycondensation and stepwise polymerization were very important in the teaching and study of polymerization chemistry.The relationship between polycondensation and stepwise polymerization,polycondensation kinetics and average degree of polycondensate were discussed,and students would be guided to know how to deal with polymeric kinetics by the derivation of the expression of the polymerization reaction rate.There were three means to control the degree of polycondensate,which would be helpful for students t... |
