초록

폴리올레핀은 광범위한 분야에서 이용되는 범용성 고분자로 물성이 우수하고 가격경쟁력이 높기 때문에 오랜 시간 동안 산업적 요구에 따라 발전하여 왔다. 그러나 폴리올레핀은 비극성 재료로서 다른 물질과의 상호 작용이 부족하기 때문에 그 용도가 제한되고 있다. 따라서 폴리올레핀 사슬에 극성기를 도입함으로써 그 응용 분야를 확장하기 위한 노력이 계속되고 있다. 폴리올레핀에 기능성을 부여하기 위하여 블록 공중합체 및 그라프트 공중합체로 대표되는 분절 공중합체를 합성할 수 있으며, 이러한 공중합체는 폴리올레핀 고유의 물성 손실을 최소화함과 동시에 기능성을 부여할 수 있다는 점에서 주목 받고 있다. 또한 리빙 라디칼 중합법을 이용하면 잘 제어된 구조와 조성을 가지는 공중합체를 제조할 수 있으며, 다양한 중합공정에 적용될 수 있다. 이에 따라, 본 리뷰에서는 리빙 라디칼 중합법을 이용한 폴리올레핀 기반 블록 또는 그라프트 공중합체의 제조 예들에 대하여 정리해 보았다.
