摘　　要：综述了CGC催化剂、单茂催化剂、多核茂金属催化剂、桥联茂金属催化剂、非茂金属催化剂催化极性烯类单体均聚合及极性烯类单体与非极性烯类单体共聚合的研究。茂金属催化剂催化极性烯类单体聚合的机理包括配位聚合机理与活性自由基聚合机理。采用茂金属催化体系可以制备极性烯类单体的均聚物及极性烯类单体与非极性烯类单体的共聚物。不仅拓宽了茂金属催化剂的应用范围,而且可开发出具有新性能的极性聚烯烃树脂。The advances in homopolymerization of polar monomers and copolymerization of nonpolar monomers with polar monomers based on CGC catalyst, half-metallocene catalyst, bis-metallocene catalyst, multinuclear metallocene catalyst, bridged metallocene catalyst, and non-metallocene catalyst are reviewed. The mechanism of polar monomer polymerization promoted by metallocene catalysts includes living radical polymerization and coordination polymerization. Polymer of polar monomer and copolymer of polar monomer with nonpolar monomer are prepared via metallocene catalysts. It not only expands the application of metallocene catalysts in polymer science, but also develops a kind of polar polyolefin resin featuring new performance.
