Abstract: 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.
