Abstract

본 발명은 고온에서 분자량 유지율이 매우 높기 때문에 열에 의한 물성의 열화가 거의 없는 말레이미드-기본코폴리머를 제공한다. 또한, 본 발명은 말레이미드-기본 코폴리머를 필요 이상으로 가열하지 않도록 하여 소량의 잔류 휘발성분만을 갖는 말레이미드-기본 코폴리머를 물성의 열화없이 효과적으로 얻을 수 있는 제조방법을 제공한다.
말레이미드-기본 코폴리머는 170℃ 또는 그 이상의 유리전이 온도, 100,000~500,000의 무게평균 분자량을 가지며 280℃에서 10분간 가열했을때 분자량 유지율이 90% 또는 그 이상이다.
이런 코폴리머를 제조할때, 휘발성분은 상기 폴리머와 휘발성분을 포함하는 폴리머 조성물을 벤트형 스크류압출기에 공급하고 이 압출기를 50-150rpm의 스크류회전수 조건하에서 작동하여 분리한다.
