摘　　要：以甲基丙烯酸-N,N-二甲基氨基乙酯为亲核试剂,分别与4-溴甲基二苯甲酮和4,4'-二(溴甲基)二苯甲酮在20℃下反应,并过简单的过滤,得到了两种水性可聚合二苯甲酮类光引发剂:4-[N-(2-甲基丙烯酰氧基乙基)二甲基溴化铵甲基]二苯甲酮(收率79.2%)和4,4'-双[N-(2-甲基丙烯酰氧基乙基)二甲基溴化铵甲基]二苯甲酮(收率79.7%)。产物用NMR、IR和元素分析进行了表征。Two novel water-soluble polymeric benzophenone photoinitiators were efficiently synthesized at 20℃ by using 2-（Dimethylamino）ethyl methacrylate,4-bromomethyl benzophenone,and 4,4′-di（bromomethyl）benzophenone as reactants,respectively.The yield of 4-[N-（2-methacyloxylethyl）dimethylammonium methyl]benzophenone was 79.2%,and that of 4,4′-bis[N-（2-methacyloxylethyl）dimethylammonium methyl]benzophenone was 79.7%.The products were characterized by IR,NMR and EA.
