Claim 0:
1. A hydrogenated styrene/conjugated diolefin copolymer, wherein the copolymer comprises a styrene-based structural unit represented by Formula 1, a hydrogenated conjugated diene-based structural unit represented by Formula 2, and a hydrogenated conjugated diene-based structural unit represented by Formula 3,, wherein R1, R2, R3, R4, R5, R6, R7, R8, and R9 are respectively H, C1-C3 alkyl, and R10 is H or C1-C4 alkyl; the content of the styrene-based structural unit is 15-50 wt %, based on the total amount of the copolymer; the content of the hydrogenated conjugated diene-based structural unit represented by Formula 3 is 8-32 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 30-80%, and the hydrogenation degree of the conjugated diolefin in the copolymer is 85-100%.
