Claims (7)

  1. α, β-에틸렌성 불포화 단량체의 수용액으로부터 중합체를 제조함에 있어, 이 단량체 수용액과 불활성 가스의 어느 한쪽의 유체의 흐름 중에 이 흐름과 같은 방향으로 다른 하나의 유체를 노즐로부터 분사함으로써 이 단량체 수용액과 이 불활성 가스를 접촉 시켜 실질적으로 용해된 산소를 제거한 단량체 수용액을 중합에 제공함을 특징으로 하는 중합체의 제조방법.
  2. 제1항에 있어서, 일방의 유체의 흐름 중에 분출되는 유체의 노즐 최협부에 있어의 분사속도가 적어도 1,000의 레이놀드 수에 상당한 방법.
  3. 제2항에 있어, 단량체 수용액 공급량에 대한 불활성 가스공급량의 비가 용량비로 0.1~10인 방법.
  4. 제1항에 있어, 일방의 유체의 흐름 중에 타방의 유체를 노즐로부터 분출 시켜서 단량체 수용액과 불활성 가스를 접촉 시키는데 아스피레이터가 사용되는 방법.
  5. 제1항에 있어, 일방의 유체의 흐름 중에 타방의 유체를 노즐로부터 분출 시켜서 단량체 수용액과 불활성 가스를 접촉 시키는데 분출기가 사용되는 방법.
  6. 제2항에 있어, 불활성 가스는 질소, 이산화탄소, 메탄과 에탄으로된 군으로부터 선택된 1종 이상의 가스인 방법.
  7. 제1항에 있어 α, β-에틸렌성 불포화 단량체의 수용액으로부터 중합체를 제조함에 있어, 중합체가 가교된 중합체인 방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
