Claims (2)

  1. 알킬렌 화합물이 열 교환 단위 앞에 있는 재순환 루우프에 도입되는 점을 특징으로하는, 기체상 2단계 방법으로 내충격성 공중합체 조성물을 생산하는 방법으로서, 이때 단중합체 상은 첫번째 단계 반응기에서 생산되고 공중합체 상은 프로필렌 및 다른 α-올레핀을 공중합시킴으로써 두번째 단계 반응기에서 생산되며, 열은, 주로 기체성인 물질 일부를 두번째 단계 반응기로부터 제거하고, 상기 물질을 열교환 단위를 함유하는 재순환 루우프를 통과시키며 냉각된 물질을 두번째 단계 반응기에 반송함으로써, 두번째 단계 반응기로부터 제거되는 방법.
  2. 제1항에 있어서, 알킬렌 화합물이 하기 일반식:
    의 알킬렌 글리콜이거나 하기 일반식의 알킬렌 글리콜 알킬렌디아민 유도체인 방법 :
    상기식에서, R 각각은 독립적으로 수소, 20개 이하 탄소 원자의 알킬 또는 20개 이하 탄소 원자의 아실이고, n은 2 또는 3이며, x 각각은 1-10의 수이고 y 각각은 0 또는 1-10의 수이다.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
