titleOfInvention | Polymerization catalyst composition and method for producing conjugated diene-based polymer |
abstract | Provided is a polymerization catalyst composition with which a conjugated diene polymer having a high cis-1,4 bond content or a conjugated diene-based copolymer having a high 1,4 bond content can be produced. The polymerization catalyst composition is characterized in that it comprises a general formula (a-1): M-(AQ 1 )(AQ 2 )(AQ 3 ) [in the formula, M is scandium, yttrium or a lanthanide; AQ 1 , AQ 2 and AQ 3 are functional groups that can be the same or different from each other; A is nitrogen, oxygen or sulfur; provided that there is at least one M-A bond] represented by a rare earth element compound (component (A)), an ionic compound (component (B)), and a cyclopentadiene skeleton-containing compound selected from the group consisting of substituted or unsubstituted cyclopentadiene, substituted or unsubstituted indene, and substituted or unsubstituted fluorene (component (C) ). |
