摘　　要：通过实验研究了偏氯乙烯悬浮聚合反应动力学 ,比较了偏氯乙烯与氯乙烯聚合动力学行为的异同 .在假定偏氯乙烯聚合反应发生在单体相和液固界面两个区域的基础上 ,提出了偏氯乙烯沉淀聚合反应速率模型 .模型预测的转化率值几乎在全转化率范围内都与本文的偏氯乙烯悬浮聚合实验结果一致 .The kinetics of suspension polymerization of vinylidene chloride was studied by experiments. Similarities and differences of the kinetics behavior were analyzed for the polymerizations of vinylidene chloride and vinyl chloride. Based on the assumption that the polymerization of vinylidene chloride includes the reactions in monomer phase and on the interface between liquid and solid phases, a kinetic rate model was proposed for the heterogeneous polymerization of vinylidene chloride. The conversion value calculated by the model is consistent well with the experimental results of vinylidene chloride suspension polymerization nearly over the entire conversion range.
