摘要:
The present invention relates to a method for producing a hydrogenated conjugated diene copolymer including a polymerization step and a hydrogenation step, wherein in the polymerization step, a conjugated diene copolymer having a high vinyl bond amount of a conjugated diene block moiety and a narrow molecular weight distribution can be produced, and in the hydrogenation step, the rate of hydrogenation is high and productivity is excellent.
