钴系催化剂催化共轭二烯烃聚合研究进展

Research progress in polymerization of conjugated dienes catalysized by cobalt based catalysts

综述了钴系催化剂在共轭二烯烃聚合领域的发展,详细总结了使用不同种类钴催化体系和含不同类型配体的钴配合物催化丁二烯、异戊二烯等共轭二烯烃聚合的催化活性和对聚合物微观结构(区域规整度、顺式-1,4-结构、反式-1,4-结构、1,2-结构和3,4-结构)及其立构规整度(间规度、等规度、微观结构序列分布)、聚合物分子量及其分布等的影响,展望了钴系催化剂在催化共轭二烯烃聚合方面的研究方向。

The development of cobalt based catalysts in the field of conjugated diene polymerization was reviewed.The catalytic activity of using different types of cobalt catalytic systems and cobalt complexes containing different types of ligands for the polymerization of conjugated dienes such as butadiene and isoprene,as well as the effect on the microstructure of polymers(regional regularity,cis-1,4-unit,trans-1,4-unit,1,2-unit,and 3,4-unit)and their stereoregularity(inter regularity,iso regularity,microstructure sequence distribution)were explored in detail with 76 references.The influence of polymer molecular weight and its distribution were also reviewed,and the research direction of cobalt catalysts in catalysizing the polymerization of conjugated dienes was prospected.
