浅谈自由基聚合动力学的教学与学习

Study and Teaching of Radical Polymerization Kinetics

自由基聚合动力学是高分子化学教学和学习中的重要内容。本文讨论了建立自由基聚合微观动力学模型的三个简化条件和三个基本假设,三个简化条件和三个基本假设是微观动力学研究聚合速率和聚合度的基础;同时也较为深入地探讨了动力学链长的物理意义、利用动力学链长概念建立起来的平均聚合度计算通用公式以及该公式的使用条件。

Polymerization kinetics is very important in the study and teaching of radical polymerization. In this presentation, the fundamental condition of radical polymerization kinetics, the expression of the polymerization reaction rate, the physical meaning of kinetic chain length, and the relationship between the number-average degree of polymerization and kinetic chain length is discussed carefully.
