PROBLEM TO BE SOLVED: To provide a hydrogenated conjugated diolefin-based polymer which is excellent in wear resistance, weather resistance, workability and the like, and can produce a tire and the like which generates little heat. SOLUTION: A conjugated diolefin polymer such as 1,3-butadiene or a copolymer of this conjugated diolefin and an aromatic vinyl compound such as styrene, which has a specific composition or the like, is hydrogenated. And at least 10%, especially 15%, of the double bonds of the conjugated diolefin bonding unit % Of a hydrogenated conjugated diolefin-based polymer is obtained. Further, after the polymerization active terminal of the copolymer is modified or coupled with a specific compound such as an isocyanate compound, an amide compound or a pyridyl-substituted ketone compound, hydrogenation can also be performed. By blending this hydrogenated conjugated diolefin polymer with various rubbers and thermoplastic resins, their impact resistance, adhesiveness, and the like can be improved. |
