摘要
在《聚合反应工程》课程中,聚合反应速率直接影响聚合产物的平均聚合度,是课程的一个核心内容,在教材中占有重要地位。不同聚合反应机理所对应的聚合反应速率不同,但它们具有很强的关联性。文中以自由基聚合、离子聚合、配位聚合以及缩聚的聚合机理为主线,把不同聚合机理中的聚合反应速率这一重要知识点做了串讲;指出了不同聚合反应速率之间的相同之处和不同之处。旨在使学生对聚合反应速率能有一个系统的认识和把握。
In the polymerization reaction engineering course,the polymerization reaction rate directly influences average polymerization degree of the polymerization products,and has the important position in the teaching material.The polymerization rate of different polymerization mechanisms is different,but they have high correlation.In this paper,The polymerization rate in the course of 'polymerization reaction engineering' was detailed based on the clue of different mechanism of free radical polymerization,ion polymerization,coordination polymerization and the condensation polymerization.The similarities and differences among different polymerization rate were pointed out,aimed at improving students to understand and grasp the definition of the polymerization rate.
