摘要： Granular poly(arylene sulfide) is recovered from a slurry comprising granular poly(arylene sulfide), polar organic solvent, alkali metal halide, poly(arylene sulfide) oligomers, untreated reactants in the water by heating the slurry under conditions to evaporate polar organic solvent, water and volatile impurities at a temperature below the normal boiling point of the polar organic solvent to produce a dry mixture containing poly(arylene sulfide), poly(arylene sulfide) oligomers and alkali metal halide which is then reslurried with water to produce a reslurried mixture containing aqueous alkali metal halide solution and dispersed poly(arylene sulfide) oligomers with the reslurried mixture being filtered through a coarse screen to recover granular poly(arylene sulfide) thereon and pass a filtrate containing poly(arylene sulfide) oligomers and aqueous alkali metal halide solution therethrough. The filtrate can be further treated by filtering through a filter aid coated vacuum filter to recover poly(arylene sulfide) oligomers thereon and pass an aqueous alkali metal halide solution therethrough as filtrate.
