Claims (6)

  1. 교반 또는 유동화 중합반응영역에서 40 내지 120℃ 온도 및 10 내지 60바의 압력하에서 단량체들을 촉매식 건조-상 공중합하고, 얻어진 고체중합체와 비전환된 기체상 단량체의 혼합물을 강하영역으로 전달하고, 감압후에 그 혼합물을 기체상(Ⅰ)을 고체상(Ⅱ)으로 분리하고, 단량체는 재순환하는 것으로 이루어진 에틸렌/α-올레핀 공중합체의 연속식 제조방법에 있어서, 고체상(Ⅱ)을 미리 기체상의 에틸렌으로 연속 세척하고, 그 다음 질소와 증기의 혼합물로 세척하는 것을 특징으로 하는 방법.
  2. 제 1 항에 있어서, 고체상(Ⅱ)의 초기 세척동안 형성된 기체상(Ⅲ)이 기체상(Ⅰ)과 함께 중합반응계로 재순환되는 것을 특징으로 하는 방법.
  3. 제 1 항에 있어서, 고체상(Ⅱ)의 초기세척은 중합반응계에 알맞은 온도 및 0.1 내지 3바의 게이지 압력하에서 수행되는 것을 특징으로 하는 방법.
  4. 제 1 항에 있어서, 고체상(Ⅱ)는 나중에 40 내지 120℃ 온도 및 0.05 내지 3바의 게이지 압력하에 증기 부화질소로 세척되는 것을 특징으로 하는 방법.
  5. 제 1 항에 있어서, 매 경우마다 고체상(Ⅱ)는 역류법에 의해 세척기체로 세척되는 것을 특징으로 하는 방법.
  6. 잔류단량체 및 향 및 방향물질이 실제로 거의 없는 잔류단량체 및 제 1 항에 따른 에틸렌 공중합체.
