摘要
对水溶性引发剂、有乳化剂存在的常规乳液聚合,水溶性引发剂无皂乳液聚合及有乳化剂存在的油溶性引发剂乳液聚合三种聚合方式,选择了水溶性相差较大的醋酸乙烯酯(VAc)和苯乙烯(St)两种单体,对其聚合动力学进行了比较,讨论了其不同的成核机理及单体水溶性对聚合速率的影响,考察了乳液的反应稳定性。结果表明聚合方式的不同、单体水溶性的不同对聚合动力学具有显著的影响。
Polymerization kinetic was studied on VAc or St normal emulsion, soap-free emulsion and oil-soluble initiator emulsion.The different nucleating mechanisms were compared.The effects of water solubility of monomer on the rate of polymerization were discussed.The results showed that the difference of the polymerization methods and the solubility of monomer are affect the polymerization kinetic seriously.
