Claims (3)

  1. 중합체 및 단량체에 대해 불활성이며 또 산소를 전혀 함유치 않는 제1의 가스흐름으로 중합체를 세정용기(purge vessel)로 운반하고, 이 세정용기에 상기 수지 및 단량체에 불활성이며 또 산소를 전혀 함유치 않은 세정가스를 공급하여, 이 세정용기내에서 상기 중합체와 세정가스를 향류 접촉시켜 상기 세정가스, 수송가스와 가스상단량체를 함유하는 제2의 가스흐름과 가스상단량체 함량이 감소된 중합체흐름을 수득하는 단계로 구성되는 가스단량체 함유 고형 올레핀 중합체로부터 미중합 가스상 단량체를 분리하는 방법.
  2. 공중합체 및 함유된 가스상 단량체에 대해 불활성이며 또 산소를 전혀 함유치 않는 제1의 가스흐름으로 공중합체를 입상으로 세정용기 상부로 운반시켜, 거의 플러그 흐름(plug flow)형태로 세정용기를 통해 하강시키고, 이 세정용기 하부에서 상기 공중합체 불활성이며 또 산소 및 가스상 단량체를 전혀 함유치 않는 세정가스를 공급하여, 이 세정용기내에서 상기 공중합체와 세정가스를 향류 접촉시켜, 상기 세정가스, 수송가스와 가스상단량체를 함유하는 제1의 가스흐름과 가스상 단량체 함량이 감소된 공중합체 흐름을 수득하고 또 제2의 가스흐름중 일부를 제1의 가스흐름으로 재순환시키는 단계로 구성되는, 가스상 단량체를 함유하는 고형의 저압중합된 저밀도 에틸렌 탄화수소 공중합체로부터 미중합 가스상 단량체를 분리하는 방법.
  3. 공중합체에 대해 불활성인 제1의 가스흐름으로 공중합체를 입상으로 세정용기 상기로 운반시켜, 거의 플러그흐름 형태로 세정용기를 통해 하강시키고, 이 세정용기 하부에서 상기 공중합체에 불활성이며 또 가스상 단량체를 함유하는 세정가스를 공급하여, 이 세정용기내에서 상기 공중합체와 세정가스를 향류 접촉시켜, 상기 세정가스, 수송가스와 다량의 가스상 단량체를 함유하는 제2의 가스흐름과 가스상 단량체 함량이 감소된 공중합체 흐름을 수득하고, 또 이 제2의 가스흐름중 일부를 상기 세정가스로 재순환시키는 단계로 구성되는 가스상 단량체를 함유하는 고형의 저압 중합된 저밀도 에틸렌 탄화수소 공중합체로부터 미중합가스상 단량체를 분리하는 방법.
