제1도는 폴리프로필렌 충격 공중합체를 생성하기 위한 2개의 반응기 종합 시스템을 나타낸다.

Claims (10)

  1. 하기 일반식(Ⅰ)의 아미노실리콘 유체로 금속 표면을 피복하고, 피막을 가수분해함으로써 경화시켜 연속 고체 피막을 형성함을 포함하여, 중합체 수지를 제조하는 동안 반응성 α-올레핀 가스에 노출된 금속 표면의 오염을 방지하는 방법.
    상기식에서, R은 각각 독립적으로 탄소수가 1내지 4인 저급 알킬이고, A는 탄소수가 2내지 6인 알킬렌 그룹이며, n은 약 5내지 약 600의 수이다.
  2. 제1항에 있어서, 금속 표면이 열 교환기의 요소인 방법.
  3. 제1항에 있어서, 반응성 가스가 지배적으로 에틸렌 또는 프로필렌 또는 이의 혼합물인 방법.
  4. 제1항에 있어서, 피막이 필수적으로 연속적인 가교 결합 고체 피막인 방법.
