摘要:
A catalyst composition for polymerizing a conjugated diene which comprises the following (a), (b) and (c) components:(a) an organolithium-aluminum compound represented by the formula:LiAlR.sup.1 R.sup.2 R.sup.3 R.sup.4(b) an organobarium-aluminum compound represented by the formula:Ba(AlR.sup.1 R.sup.2 R.sup.3 R.sup.4).sub.2 or Ba[AlR.sup.1 R.sup.2 R.sup.3 (OR.sup.4)].sub.2(c) a lithium alkoxide represented by the formula:LiOR.sup.5 The conjugated diene polymer or copolymer obtained by polymerizing a conjugated diene alone or in combination with other monomer with the above catalyst composition in an inert organic solvent has a high trans-1,4 bond content, a low vinyl bond content and a low cis-1,4 bond content.
