摘要
对苯乙烯本体聚合反应动力学基础实验进行了改造与拓展,利用直接沉淀称重法代替膨胀计法,在有限的课时安排中完成对聚合反应速率和聚合物相对分子质量的测定,增加了实验的直观性和综合性,加深了学生对聚合反应动力学的认识.
The basic experiment of kinetic study on styrene bulk polymerization was improved and expanded.The direct weighing method through precipitation was used to replace the means of dilatometer.In limited hours arrangements,the polymerization rate and relative molecular weight of polymer were both obtained.As a result,the visibility and comprehensiveness of the experiment were increased and students could understand reaction kinetics of polymerization more deeply.
