摘　　要：聚烯烃材料年产量巨大,用途广泛,与人类生产生活密切相关.聚烯烃研究领域的核心在于催化剂,催化剂的性能往往决定了聚烯烃的性质.因此,高性能的催化剂设计与合成成为研究的一大热点.随着科技工作者的不懈努力,大量的催化剂相继问世.其中钴配合物是一类十分重要的烯烃聚合催化剂,它能够用于催化多种单体聚合.这些钴配合物结构丰富,配位原子种类多样(例如N、O、P、S等),且合成简便.因此,通过对催化剂结构进行精确调控,可以实现提高其催化活性、调整聚合物的微观结构、改善聚合物的宏观性能等目的.综述了钴配合物在乙烯、共轭二烯、降冰片烯、丙烯酸酯等常见单体均聚中的应用,并从结构的角度将钴配合物进行了分类.此外,还详细讨论了催化剂结构、助催化剂、反应温度等因素对催化剂活性、聚合物分子量以及聚合物微观结构等性质的影响,期望为钴配合物的设计与合成提供参考.Polyolefin materials have huge annual output and wide applications,which are closely related to human production and life closely.The core of polyolefin research lies in the catalyst,the performance of which often determines the properties of polyolefins.Therefore,the design and synthesis of high-performance catalyst have become a hot research topic,and a large number of catalysts have come out.Cobalt complexes are very important kind of olefin polymerization catalysts,which can be used to catalyze a variety of monomer polymerization.These cobalt complexes are structure diversity and have a variety of coordination atoms(such as,N,O,P,S etc.),and the synthesis is relatively simple.Therefore,the structure of the catalyst can be precisely regulated to improve the catalytic activity,adjust the microstructure of the polymer,and improve the macroscopical properties of the polymer.In this paper,the applications of cobalt complexes in homopolymerization of ethylene,conjugated dienes,norbornene,acrylates and other common monomers are reviewed,and the cobalt complexes are classified from the perspective of structure.What’s more,the effects of catalyst structure,temperature,cocatalyst on catalyst activity,polymer molecular weight and polymer microstructure are discussed in detail.It is expected to provide a reference for the design and synthesis of cobalt complexes in the future.
