Abstract

중합 구역 및 상위에 위치한 기체 유속 강소 구역을 포함하는 하나 이상의 유동상 반응기에서 CH2=CHR의한 종 이상의 기상 올레핀의 연속 중합 공정이 수행된다. 유동상 반응기는 기체 리사이클 배관에 연결되어 있고, 이것은 반응기의 상부에서 유출하는 기체가 압축, 냉각되어 다시 반응 구역하부 위치에 있는 반응기로 이송시키는 수단과 같은 압축 및 냉각 장치를 포함하고 있다. 상기 공정은 구성 단량체 또는 단량체들이 직접적으로 상기 유동상 위의 하나 이상의 위치에서 상기 유동상 반응기로 이송되는 것을 특징으로 한다.
