Description

에멀젼중합에 있어서 비닐수지유액의 한외여과와 침투물의 재사용
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (1)

  1. 수용액상 반응매체를 함유하는 반응구역에서 중합될 단량체 또는 단량체들, 중합되는 단량체(들) 100중량부분에 대한 0.02-1.0 중량%의 자유기를 제공하는 촉매, 에멀젼 유화제들을 약 30°-70℃의 온도 범위에서 예비혼합시켜서 비닐수지 유액을 만들고 이 유액을 한외여과 구역으로 보내어 그곳에서 유액이 강압적으로 반투과성막을 통과하면서 총고체들의 약 30%-약 60% 범위에 해당하는 비닐 중합체 입자를 뒤에 남기고 한외여과 구역으로부터 나오는 침투물은 반응구역으로 순환되어 수용액상 반응매체로 쓰이며, 또한 유액형태의 비닐중합체 입자들을 건조구역으로 통과시켜 중합체 또는 공중합체를 분말형태로 회수하는 공정으로 구성되며 앞서의 침투물을 사용할 경우 중합체의 누적이 상당히 감소되는 잇점이 있는 비닐과 비닐리덴 할로겐화물의 중합체 및 그 상호간, 또는 적어도 하나의 종말 CH2=C< 그룹을 갖는 하나 또는 그 이상의 비닐리덴 단량체와의 공중합체들의 제조공정.
