The development of cobalt based cata-lysts in the field of conjugated diene polymerization was reviewed.The catalytic activity of using different types of cobalt catalytic systems and cobalt complex-es containing different types of ligands for the poly-merization of conjugated dienes such as butadiene and isoprene,as well as the effect on the microstruc-ture 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,mi-crostructure 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 cata-lysts in catalysizing the polymerization of conjugated dienes was prospected.
