Abstract
본 발명은 고분자량 폴리아릴렌설파이드의 제조방법에 관한 것으로서, 더욱 상세하게는 고분자량 폴리아릴렌설파이드를 제조하는 과정에서 알카리금속황화합물의 수화물과 수화물과 중합조제의 혼합물을 탈수시킬 때 탈수조제를 첨가함으로써 탈수효율을 향상시킨 다음에 중합반응시키므로써 각종 물성이 우수하고 필름 및 섬유화에도 적합한 고분자량 폴리아릴렌설파이드를 제조하는 방법에 관한 것이다.The present invention relates to a method for preparing high molecular weight polyarylene sulfide, and more particularly, to dehydrating a hydrate of an alkali metal sulfur compound and a mixture of a hydrate and a polymerization aid in the process of preparing a high molecular weight polyarylene sulfide. The present invention relates to a method for producing a high molecular weight polyarylene sulfide which is excellent in various physical properties and suitable for film and fiberization by improving the dehydration efficiency and then polymerizing the reaction.
