Polyolefin is one of the most important commodity polymers having excellent physical properties and cost competitiveness, which has continuously broadened their market in response to a heavy demand from industry. However, the lack of polarity in polyolefin has limited its applications, especially wh...

폴리올레핀 특징? | 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. | |
폴리올레핀의 제한점? | 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. | |
β-hydride elimination 반응의 장점? | 상용 폴리프로필렌의 열분해로 얻어진 말단이 불포화된 폴리프로필렌은 브롬화를 통해 ATRP개시제로 사용할 수 있다29. 이 반응은 allylic bromide 위치에서 개시하여 사슬연장반응이 높은 효율로 진행된다는 장점이 있으나, 불포화 결합부위에 개시 site를 도입하는 것이 쉽지 않다는 단점 또한 가지고 있다. |
