Beschreibung
Zusammenfassung:	One embodiment of the present invention provides a copolymer including an aromatic vinyl-based monomer and a conjugated diene-based monomer, wherein an aromatic vinyl-based content is 35 to 45 wt%, a vinyl content is 25 to 35 wt%, a molecular weight distribution is 1.0 to 1.2, and an aromatic vinyl-based block content is less than 1 wt%. The copolymer has a high aromatic vinyl content and a low molecular weight distribution while suppressing the production of aromatic vinyl blocks. 본 발명의 일 실시예는 방향족 비닐계 단량체, 공액 디엔계 단량체를 포함하고, 방향족 비닐계 함량이 35~45중량%이고, 비닐 함량이 25~35중량%이고, 분자량분포가 1.0~1.2이고, 방향족 비닐계 블록의 함량은 1중량% 미만인, 공중합체를 제공한다.
