摘　　要：1,3-二烯烃类单体聚合物性能优异,在橡胶工业中占据重要地位.以1,3-丁二烯为单体的顺丁橡胶在工业中可生产多种橡胶制品,以异戊二烯为单体的异戊橡胶因其结构与天然橡胶相似,在一些领域可替代天然橡胶.1,3-二烯类聚烯烃材料的发展大大依赖于聚烯烃催化剂的不断创新.在过去的10年中,铁、钴催化剂因其原材料廉价、配位类型丰富、合成简便、性质稳定等优良特性受到了广泛关注.通过对催化剂的配体结构进行合理设计和调整,能控制聚合物的微观结构、分子量,从而改变聚合产物的性能.本文综述了近10年来铁、钴配合物催化1,3-二烯烃聚合的研究进展,详细讨论了催化剂结构对催化活性、聚合物分子量、聚合物微观结构和聚合物分子量分布的影响.Polymers of 1,3-diene monomers have excellent properties and play an important role in rubber industry.Polymers of 1,3-diene monomers is synthesized from 1,3-butadiene,and it can be fabricated into a variety of rubber products,while isoprene rubber can replace natural rubber in some fields due to its similar chemical structure with natural rubber.The key to the polymerization of 1,3-diene monomers is the catalyst.In the past decade,iron and cobalt catalysts have received much attention due to their excellent properties such as inexpensive raw materials,abundant ligand types,simple synthesis and stable properties.Rational design and synthesis of the catalyst structures has enabled good control over the stereoselectivity,molecular weight,and thus improve their performance of the polymerization product.This paper reviews the research progress of iron and cobalt complex-catalyzed 1,3-diene polymerization in the last decade and discusses in detail the influence of catalyst structure on catalytic activity,polymer molecular weight,polymer microstructure and polymer molecular weight dispersity.
