폴리올레핀 블록공중합체 열가소성 탄성체
Polyolefin Block Copolymer Thermoplastic Elastomer
최근 메탈로센 촉매를 통한 올레핀 합성 기술의 발달로 폴리올레핀 블록공중합체를 제조할 수 있는 기술이 개발되었으며 향후 고분자 산업에 크게 기여할 것으로 기대되고 있다. 하지만 현재까지 폴리올레핀 블록공중합체의 특성에 대한 체계적인 연구가 보고되고 있지 못한 실정이다. 본 리뷰 논문에서는 결정질의 poly(ethylene) (E) 블록과 고무질(rubbery)의 블록을 가지는 선형 폴리올레핀 블록공중합체를 통하여 폴리올레핀 블록공중합체의 열가소성 탄성체로서의 열역학적, 기계적 특성 및 분자 구조의 효과 특성 등에 관하여 살펴보고자 한다.
Polyolefin block copolymer has been taking a great deal of attention due to their great potential in polymer industry since a new metallocene catalytic method for producing polyolefin block copolymer was developed by Dow Chemicals. However, so far, there was no systematic study of olefin block copolymer. In this review, Linear polyolefin block copolymers, containing semicrystalline poly (ethylene) (E) blocks and a rubbery block as a thermoplastic elastomer, were investigated in the viewpoint of microphase separation mode, microstructure, deformation behavior, and molecular architecture.
