摘要(Abstract)：

以对氯甲基苯乙烯（VBC）和碘化钠（NaI）反应原位生成引发剂单体，经自缩合可逆络合聚合（SCVP-RCMP）一步法制备了支化聚甲基丙烯酸甲酯。通过核磁共振（NMR）和三检测凝胶渗透色谱（TD-GPC）对聚合物和聚合反应过程进行了分析和表征。结果表明，模型化合物苄氯（BzCl）在80℃与碘化钠（NaI）反应10 min就完全转化成苄碘。VBC能与NaI反应并成功引发MMA发生RCMP，MMA的转化率高达98.1%，所得聚合物特性黏度低于同分子量下线型聚合物的特性黏度，具有明显的支化结构。聚合物支化度随NaI用量的增加而增加。对反应过程研究表明，聚合反应6 h之前具有"活性"可控的特点，反应时间延长，聚合物支化度增加。
