Abstract

본 발명은, 적어도 아크릴로니트릴계 단량체를 필수성분으로서 함유한 단량체를 괴상 또는 용액중합에 의해 단량체를 증발시키면서 80℃ 이상의 온도에서 (공)중합하는 방법에 있어서, 반응조내에 하부중합액에 대하여 상부에 기상부분을 형성할때, 이 기상의 온도를 30~65℃로 유지하고, 실질적으로 하부중합액으로부터의 증발증기를 반응조의 외부에 내지 않고 중합하는 것을 특징으로 하는 (공)중합체의 제조방법을 제공하는 것으로서, 본 발명의 방법에 의해, 반응조기상부를 냉각하고, 특정한 온도로 유지함으로써 기상부에서의 미반응모노머의 중합을 억제하고, 겔화한 폴리머가 제품속에 혼입하는 일없이, 또한 중합시의 반응열을 효율적으로 제거할 수 있는 것이다.
