블록 공중합체, 적어도 하나의 부텐의 단독중합체 또는 공중합체, 및 적어도 하나의 올레핀 단독중합체 또는 공중합체를 함유하고, 상기 블록 공중합체가 비중이 0.85g/cc 초과인 수소화된 저 비닐 폴리부타디엔 말단 블록 및 폴리알케닐 아렌/수소화된 디엔의 조절된 분포의 중간블록을 보유하는, 조성물이 개시된다. 이 블록 공중합체는 트리블록 공중합체로써 바람직한 선형 구조이지만, 적어도 2개의 암(arm) 또는 그 이상을 가진 분지형 또는 방사형 커플링된 공중합체일 수도 있다. 이 조성물은 자동차 시장 등에서 디젤 연료 등과 같은 화학물질에 내성인 물품을 제조하기 위한 회전 성형, 슬러시 성형, 사출 성형, 압출 또는 압축 성형, 또는 열성형 또는 캘린더링에 유용하다. 이 블록 공중합체의 MFR은 2.16kg의 중량과 230℃에서 1 내지 약 50g/10min이다. A composition is disclosed, comprising a block copolymer, at least one homopolymer or copolymer of butene, and at least one olefin homopolymer or copolymer, wherein said block copolymer has hydrogenated low-vinyl polybutadiene end blocks with a specific gravity>0.85 g/cc, and a controlled distribution midblock of polyalkenyl arene/hydrogenated diene. Although the block copolymer has a preferred linear structure as a triblock copolymer, it may also be branched or radial coupled copolymer that has at least 2 arms or more. The composition is useful for rotational molding, slush molding, injection molding, extrusion or compression molding, or thermoforming or calendering for making articles that are resistant to chemicals such as diesel fuel, for the automotive market, for example. The MFR of the block copolymer is 1 to about 50 g/10 min. at 230° C., with a wt. of 2.16 kg.
