摘要: 在建立复合引发剂分解动力学模型的基础上,推导了复合引发剂体系引发下的氯乙烯(VC)悬浮聚合动力学模型.用模型预测不同温度、引发剂复合体系引发的氯乙烯聚合动力学与实验数据能较好地吻合.其中TxEHP,Tx99,Tx23和Tx36在51和57℃下的引发效率由单一引发剂引发的VC动力学数据计算

Abstract: On the basis of the decomposition kinetic model of peroxide mixture, a kinetic model of vinyl chloride suspension polymerization with peroxide mixture as initiator was derived and can be used to predict the kinetics of vinyl chloride polymerization in good agreement with the experimental data.The initiator efficiency of TxEHP, Tx99, Tx23 and Tx36 at51 or57 ℃ was obtained from the kinetic data of VCpolymerization initiated by single initiator

Key words: Peroxide mixture, Vinyl chloride, Polymerization kinetics
