摘要
聚烯烃由于其优异的自身性能,成为广泛应用于人类日常生产生活中的高分子材料,茂金属催化剂作为聚合烯烃中单一活性中心的催化剂发展迅速,成为聚烯烃催化剂行业的研究热点。综述了非桥联型、桥联型和限制几何型三类茂金属催化剂的基本性质,以及在各类烯烃聚合过程中的应用现状,对它们在烯烃聚合过程中的区别进行了阐述,并对包括茂金属催化剂在内,其他单一活性中心的烯烃聚合催化剂进行了前景展望。
Due to its excellent properties,polyolefin has become a polymer material widely used in human daily production and life.Metallocene catalysts have developed rapidly as a single active center catalyst for polymerizing olefins,and have become a research hotspot in the polyolefin catalyst industry.The basic properties of the three types of non-bridged,bridged and restricted geometry metallocene catalysts were reviewed,and their application status in various olefin polymerization processes were reviewed.The differences between them in the olefin polymerization process were described,and including metallocene catalysts,other single-site olefin polymerization catalysts were prospected.
