通过电子转移活化原子转移自由基聚合(AGET ATRP),以2-溴代异丁酸乙酯(EBiB)为引发剂、维生素C(VC)为还原剂.以碱性离子液体1-丁基-3-甲基咪唑氢氧化盐([Bmim][OH])分别和FeCl3·6H2O、CuCl2及RuCl3形成的配合物为催化剂催化甲基丙烯酸甲酯(MMA)的本体和溶液聚合.催化量的[Bmim][OH]即可提高聚合速率,并且得到相对分子质量分布可控的PMMA (Mw/Mn为1.20～1.40).研究了[Bmim][OH]的加入量对聚合速率和相对分子质量分布的影响,3种催化体系催化性质通过循环伏安曲线表征.扩链反应证明了碱性离子液体催化甲基丙烯酸甲酯的聚合为“活性”/可控自由基聚合.碱性离子液体良好的溶解性使其成为活性自由基聚合的良好催化剂.
