摘　　要：在茂金属催化烯烃聚合过程中,金属配合物催化剂通常需要被助催化剂活化,生成活性中间体后催化烯烃插入聚合反应。对铝氧烷类、硼烷类、强酸类、碳正离子类及其他类型助催化剂进行了综述,分析了化学结构、合成方法及其在烯烃配位聚合中的表现。并对助催化剂的未来发展趋势进行展望。In the process of metallocene-catalyzed olefin polymerization,metal complexes usually need to be activated by cocatalysts to generate active species that can truly promote the olefin insertion reaction.Cocatalysts such as aluminoxane,borane,strong acid,and carbonium were reviewed.Their chemical structure,polymerization mechanism,and performance in the polymerization process were analyzed.The future of cocatalysts was also prospected.
