- 반응 개시제 존재하에 우선 모노머 혼합물을 교반오토클레이브에 통과시킴으로써 일부를 중합시키고 그후에 상기오토클레이브로부터 반응 혼합물을 배출시켜 열교환기에 통과시킴으로써 미리 정해진 온도까지 냉각시킨 다음, 계속하여 반응혼합물을 냉각시키지 않은 관상반응기를 통과시킴으로써 단열 조건하에서 더욱 중합시킴을 특징으로 하여 오토클레이브와 이 오토클레이브에 연속적으로 연결된 관상반응기를 사용하여 반응개시제 존재하에 100°내지 400℃의 온도 및 약 500kpa의 압력에서 에틸렌을 임의로 하나 이상의 공중합 가능한 화합물과 함께 중합시켜 폴리머 또는 코폴리머를 제조하는 방법.
- 제 1 항에 있어서, 오토클레이브로부터 배출된 혼합물을 관상반응기에 주입시의 온도가 220°내지 250℃가 되도록 냉각시킴이 특징인 방법.
- 제 1 항에 있어서, 관상반응기내의 최고 온도를 250°내지 290℃로 조정함이 특징인 방법.
