Claim 1:
2. The hydrogenated styrene/conjugated diolefin copolymer of claim 1, wherein the content of the styrene-based structural unit is 25-35 wt %, based on the total amount of the copolymer; the content of the hydrogenated conjugated diene-based structural unit represented by Formula 3 is 10-30 wt %, based on the total amount of the hydrogenated conjugated diene-based structural unit represented by Formula 2 and the hydrogenated conjugated diene-based structural unit represented by Formula 3; the randomness degree of the styrene-based structural unit in the hydrogenated conjugated diene-based structural unit is 35-75%, and the hydrogenation degree of the conjugated diolefin in the copolymer is 95-100%.
