摘　　要：以苯乙烯(St)和甲基丙烯酸环氧丙酯(GMA)为单体,2,2’-偶氮双[2-(2-咪唑啉-2-基)丙烷]盐酸盐(VA-044)为引发剂,无皂乳液共聚,重点研究了苯乙烯和甲基丙烯酸环氧丙酯共聚体系的动力学特性和聚合反应速率的影响因素,考察了引发剂、功能单体浓度、聚合温度等因素对聚合反应动力学行为的影响.P（styrene-co-glycidyl methacrylate） were prepared by soap-free emulsion polymerization in the presence of 2,2＇-Azobis[2-（2-imidazolin-2-yl）propane] dihydrochloride（VA-044） as an initiator. In soap-free emulsion copolymerization experiments of styrene and glycidyl methacrylate, the dynamic characteristics of St-GMA copolymerization system and factors affecting polymerization rate were studied. Effects of initiator, concentration of functional monomer, polymerization temperature on the kinetics of the copolymerization were investigated.
