Effective initiations and high molecular weight polymers with unimodal molecular weight distributions could be easily obtained by varying the reaction parameters of systems under mild conditions. Although these aluminum compounds were inefficient initiators for methyl methacrylate （MMA） polymerization, they exhibited remarkable catalytic activity for butyl methacrylate （BMA） polymerization, affording high molecular weight poly（BMA）s.展开更多
