摘　　要：介绍了以过氧化苯甲酰为引发剂 ,甲基丙烯酸 - 2 -羟丙酯与甲基丙烯酸乙酯进行的共聚合反应。通过测得共聚物中羟基的含量确定了共聚物的组成 ,且以线性化方法求出共聚反应中两种单体的竞聚率 ,所得结果为γHPMA=1 80 ,γEMA=0 2Benzoyl peroxide was used as initiater,2 hydroxypropyl methacrylate was copolymerized with ethyl methacrylate in bulk polymerization.The copolymer compositions were determined from hydroxy content,the reactivity ratios have been calculated by linearization method.The reactivity ratios are γ HPMA =1 80,γ EMA =0 24。

关 键 词：甲基丙烯酸-2-羟丙酯 甲基丙烯酸乙酯 共聚合 竞聚率
