Abstract
(a) 프로필렌 및 에틸렌 및/또는 4개 내지 10개의 탄소 원자를 갖는 알파-올레핀의 존재 하에 고속 유동화 조건 하에 상승관인 상기 중합 영역의 첫번째를 통해 흘러서, 랜덤 프로필렌 공중합체(RACO)를 수득하고;
(b) 상승관을 떠나고, 프로필렌 및 에틸렌 및/또는 4개 내지 10개의 탄소 원자를 갖는 알파-올레핀의 존재 하에 고밀도화 형태로 이들이 아래로 흐르는 하강관인 상기 중합 영역의 두번째에 진입하여서(여기서, 하강관에서의 에틸렌 및/또는 알파-올레핀의 농도는 상승관에서보다 높음), 엘라스토머 프로필렌 공중합체(BI PO)를 수득하고;
(c) 하강관을 떠나고, 상승관으로 재도입되어서, 상승관과 하강관 사이에 중합체의 순환을 확립하는, 방법.
