| 摘 要： | 研究了叔丁醇亚铜为催化剂、四种卤代烃OET基氯、正丁基溴、叔丁基氯、叔丁基溴）为引发剂的甲基丙烯酸甲酯的聚合反应。考察了催化剂用量、引发剂和催化剂比例、聚合温度、单体浓度以及卤代烃中烷基结构和卤素等因素对聚合反应的影响。聚合反应具有明显的诱导期，不同聚合反应时间的转化率和聚合物分子量之问不呈线性关系，表明本聚合反应并不具有活性特征。

| Abstract: | The polymerization of methyl methacrylate by copper(I)t-butoxide with n-butyl chloride,n-butyl bromide,t-butyl chloride and t-butyl bromide is studied. The effect of polymerization conditions is investigated including the quantity of use of catalyst,the ratio of initiator to catalyst,polymerization temperature,monomer concentration as well as the structure and component of alkyl halids. The polymerization has an obvious inducing period. The relationship between the yield of polymer and the molecular weight is not linear. Hence the polymerization is not living. |
