Abstract

본 발명은 알리렌설파이드 중합체의 제조방법에 관한 것으로, 더욱 상세하게는 유기극성용매와 알카리금속 수황화물의 혼합물을 탈수시킬 때 일정량의 유기극성용매를 일정 온도에서 분사 투입시키므로써 탈수효율을 향상시켜 분자량이 증가된 아릴렌설파이드 중합체를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing an aliene sulfide polymer, and more particularly, by dewatering a mixture of an organic polar solvent and an alkali metal hydrosulfide at a predetermined temperature by spraying a certain amount of the organic polar solvent to improve the dehydration efficiency. The present invention relates to a process for preparing arylene sulfide polymers having increased molecular weight.
