A polymer composition comprising a star-branched copolymer having a plurality of arms is disclosed. Each polymer arm has a molecular weight of 1 to 50 kg/mol and includes: a polymerization unit (i) derived from a first vinyl aromatic monomer comprising a radical-reactive group, wherein greater than 10 mol% and not greater than 100 mol% of the unit (i) is not hydrogenated; a polymerization unit (ii) optionally comprising a high Tg monomer and the polymerization unit (i) in a hydrogenated form or a polymerized styrene unit in a hydrogenated form; and a polymerization unit (iii) optionally comprising a polymerization unit (a) in hydrogenated form derived from at least one acyclic conjugated diene, and a polymerization unit (b) derived from at least one second vinyl aromatic monomer, wherein less than 10 wt% of the unit (a) is not hydrogenated. 복수의 암(arm)을 갖는 스타-브랜치 공중합체를 포함하는 중합체 조성물이 개시된다. 각각의 중합체 암은 1 kg/mol 내지 50 kg/mol의 분자량을 가지며, 하기를 포함한다: 래디칼-반응성 기를 포함하는 제 1 비닐 방향족 단량체로부터 유도된 중합 단위(i), 여기서 상기 단위(i)의 10 mol% 초과 내지 100 mol% 는 수소화되지 않은 것임; 및, 선택적으로, 고 Tg 단량체, 및 수소화 형태의 중합 단위(i) 또는 수소화 형태의 중합된 스티렌 단위를 포함하는 중합 단위(ii); 및, 선택적으로, 하나 이상의 비환식 공액 디엔으로부터 유도된 수소화된 형태의 중합 단위(a), 및 하나 이상의 제 2 비닐 방향족 단량체로부터 유도된 중합 단위(b)를 포함하는 중합 단위(iii), 여기서 단위 (a)의 10 중량% 미만은 수소화되지 않은 것임.
