본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (4)

  1. 중합 또는 공중합에 의하여 제조되고, 그의 주성분으로서 주쇠에 연결된 옥시메틸렌 라디칼을 갖는 조(祖)폴리아세탈 중합체를 80℃이상이고 중합체의 융점이하인 온도와 이질 평형상태에 있는 비-용해성 액상매제내에서 처리하는 경우, 접촉처리가 조 중합체와 비-용해성 매제를 서로 상대방향으로 이동시킴으로써 수행되는 것을 특징으로 하는 폴리아세탈 중합체의 제조방법.
  2. 제1항에 있어서, 조 폴리아세탈 중합체가 주쇠에 둘이상의 인접 탄소원자를 갖는 옥시알킬렌 라디칼을 소유하는 공중합체인것을 특징으로 하는 폴리아세탈 중합체의 제조방법.
  3. 제1 또는 2항에 있어서; 비-용해성 액상매제가, 주로 물로 된 비-용해성 액상매제인 것을 특징으로 하는 폴리아세탈 중합체의 제조방법.
  4. 제1내지 제3항중 어느 하나에 있어서, 비-용해성 액체가 7이상의 PH를 갖는 비-용해성 액상매제인 것을 특징으로 하는 폴리아세탈 중합체의 제조방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
