| titleOfInvention | Process for producing hydrogenated conjugated diene copolymer |
| abstract | (Problem) In the polymerization step, it is possible to produce a conjugated diene copolymer having a high vinyl bond content in the conjugated diene block portion and a narrow molecular weight distribution, and in the hydrogenation step, the hydrogenation speed is high, resulting in high productivity. Provided is a method for producing an excellent hydrogenated conjugated diene copolymer. (Solution) A polymerization step of copolymerizing a conjugated diene monomer and a vinyl aromatic monomer using an initiator composed of an organolithium compound, and a conjugated diene copolymer obtained by the polymerization step, In the polymerization step, the organic lithium compound, the ether compound (A) having two or more oxygen atoms, and the alkali metal alkoxide (B) in the following molar ratio. A method for producing a hydrogenated conjugated diene copolymer, which coexists. (A) / Organic lithium compound is 0.2 or more and less than 3.0 (B) / Organic lithium compound is 0.01 or more and 0.3 or less. |
