Beschreibung
Zusammenfassung:	One embodiment of the present invention provides a copolymer comprising: a first part including an aromatic vinyl-based monomer and a conjugated diene-based monomer; and a second part including an aromatic vinyl-based monomer and a conjugated diene-based monomer, wherein a content of the aromatic vinyl-based monomer is 35 to 45 wt% based on the total weight of the copolymer and satisfies formula 1, V_1 > V_2. In formula 1, V_1 is a vinyl content of the first part, and V_2 is a vinyl content of the second part. According to one aspect, the present invention can provide a copolymer with a high content of an aromatic vinyl-based monomer and excellent compatibility with a conjugated diene-based copolymer. 본 발명의 일 실시예는 방향족 비닐계 단량체 및 공액 디엔계 단량체를 포함하는 제1 부; 및 방향족 비닐계 단량체 및 공액 디엔계 단량체를 포함하는 제2 부;를 포함하고, 공중합체 총 중량을 기준으로 방향족 비닐계 단량체의 함량은 35~45중량%이고, 하기 식 1을 만족하는, 공중합체를 제공한다.
