Abstract:
The present invention provides 1) a complex comprising a mono-anionictridentate ligand, represented by the following general formula (I); 2) a polymerization catalyst composition, comprising the complex; and 3) a cis-1,4-isoprene polymer, a cis-1,4-butadiene polymer, a cis-1,4-isoprene-styrene copolymer, a cis-1,4-butadiene-styrene copolymer, a cis-1,4-butadiene-cis-1,4-isoprene copolymer, and a cis-1,4-butadiene-cis-1,4-isoprene-styrene copolymer, each of which has high-cis-1,4 content in a micro structure and a sharp molecular-weight distribution.
