Abstract

전체 MIL 값이 ＞2g/10분이고, 135℃ 에서 테트라히드로나프탈렌 중의 전체 [n] 값은 ≤2.8㎗/g이며, Mw/Mn값은 ＞20이고, 25℃에서 크실렌에 불용성인 분획은 ≥94이며, [n]≥2.6을 갖는 분획(A)를 10∼60중량%함유하는 결정성 프로필렌 중합체 및 공중합체를 특히 마그네슘 할로겐화물상에 지지된 찌글러-나타 촉매의 존재하에서 적어도 두단계의 연속 중합으로 제조한다.
상기 중합체는 높은 용융강도, 높은 기계적 특성을 가지며 얇은 시이트를 열성형하는 압출 성형뿐만 아니라 사출성형 및 중공성형 등의 각종 전환 기술을 사용한 성형품 제조용으로 특히 적당하다.
