摘要: This invention relates to a method for producing copolymer of conjugated diene compound and an unconjugated olefin other than the having high cis-1,4 bond content portion, more particularly characterized by comprising step polymerizing in presence polymerization catalyst composition including at least one complex selected from metallocene represented following general formula (I): (wherein M is lanthanoid element, scandium or yttrium, CpR independently non-substituted substituted indenyl, Ra-Rf are alkyl group carbon number 1-3 hydrogen atom, L neutral Lewis base, w integer 0-3) so on.
