摘　　要：讨论了采用溶液聚合方法甲基丙烯酸缩水甘油酯和甲基丙烯酸甲酯共聚问题中投料方式、链转移剂用量、反应温度、甲基丙烯酸缩水甘油酯和甲基丙烯酸甲酯的不同比例对于甲基丙烯酸缩水甘油酯甲基丙烯酸甲酯共聚物数均分子量、重均分子量及分子量分布的影响。通过控制这些条件可以得到分子量和分子量分布可控的甲基丙烯酸缩水甘油酯甲基丙烯酸甲酯共聚物。It is that the effection of raw material feeding pattern, chain transfer agent dosage, reaction temperature and ratio of glycidyl methacrylate and methyl methacrylate to number-average molecular weight, weight-average molecular weight and molecular weight distribution in glycidyl methacrylate and methyl methacrylate copolymerization by solution polymerization method. By controlling these conditions, glycidyl methacylate and methyl methacrylate copolymer of controllable molecular weight and molecular weight distribution was obtained.
