Abstract

폴리(아릴렌 설파이드) 중합체로부터 올리고머 및 비-중합체 불순물을 제거하고 중합체를 손쉽게 회수가능한 미립 형태로 생성하는 방법이 제공되며, 이때 올리고머 및 비-중합체 불순물과 희합된 폴리(아릴렌 설파이드)는 중합체, 올리고머 및 불순물을 실질적으로 용해하기 충분한 온도에서 용매, 물, 및 임의로 염기와 접촉된 후；용액은 올리고머 및 불순물이 용액에 잔류하는 반면 폴리(아릴렌 설파이드)는 침전되는 온도로 냉각되고, 그리고 나서 침전된 중합체는 올리고머 및 분순물을 함유하는 용액으로부터 분리된다. 이 방법에 의해 생성된 중합체 생성물이 또한 기재되어 있다.
