Beschreibung
Zusammenfassung:	Provided is random copolymerization in which the particle size and moisture content of a crumb can be appropriately controlled. The present invention comprises a random copolymer in which an aromatic vinyl monomer unit, a conjugated diene monomer unit, and an ethylene structure are contained, a molecular weight distribution by GPC is unimodal, and a molecular weight distribution is 1.30 to 1.75. [과제] 크럼의 입경 및 함수율을 적절하게 제어 가능한 랜덤 공중합을 제공한다. [해결수단] 방향족 비닐 단량체 단위, 공액 디엔 단량체 단위, 및 에틸렌 구조를 갖고, GPC에 의한 분자량 분포가 단봉성이며, 분자량 분포가 1.30 내지 1.75인, 랜덤 공중합체.
