Process for the purification of polyarylene sulfide |
| abstract |
Provided is a method of purifying a polyarylene sulfide by washing it with a mixture of an aprotic organic solvent and an alkyl halide, or with a mixture prepared by adding a halogenoaromatic compound having an electron-withdrawing group to an aprotic organic solvent. The method makes it possible to reduce the impurities such as alkali metal halides in polyarylene sulfide, thus giving thermally stable polyarylene sulfide. |
