采用示踪剂法对氯乙烯悬浮聚合动力学试验技术进行了研究，所得到的氯乙烯聚合转化率与重量法转化率结果吻合较好，并对不同引发体系和变温聚合工艺的氯乙烯聚合体系进行了聚合动力学考察，可为优化引发剂体系、缩短聚合时间和提高聚合产能提供理论基础。%Tracer method was used to study the kinetics of vinyl chloride polymerization. The polymerization conversion rate was in good agreement with that by gravimetrie method. Meanwhile, kinetics of vinyl chloride polymerization at different initiator systems and different temperature were investigated. This method could offer theoretical data to optimize the initiator system, shorten polymerization time and improve polymerization production.
