通过甲基丙烯酸叔丁酯（tBMA）（A）和环氧乙烷（EO）（B）两种共聚单体的连续活性阴离子聚合，制备了结构明确的AB（BA）、阿坝和BA B嵌段共聚物，与它们的加入顺序无关。在所有情况下，嵌段共聚物的分子量和组成可以基于单体与引发剂的摩尔比来预测，并且分子量分布相对窄。结果表明，嵌段共聚进行无均聚物形成，也没有副反应。定量水解PtBMA块
Well-defined AB (BA), ABA, and BAB block copolymers of tert-butyl methacrylate (tBMA) (A) and ethylene oxide (EO) (B) were prepared by sequential living anionic polymerization of the two comonomers, irrespective of their addition order. In all cases, molecular weight and composition of the block copolymers can be predicted on the basis of the monomer over initiator molar ratio, and the molecular weight distribution is relatively narrow. The results suggest that block copolymerization proceeds without homopolymer formation nor side reactions. The PtBMA blocks were quantitatively hydrolyzed
