Abstract: Provided is a method for manufacturing fine polyarylene sulfide (PAS) powder, in which impurities such as alkali metal salts and/or PAS oligomers are reduced while the wettability of the fine PAS powder in a fine PAS powder-containing solid is retained after solid-liquid separation of a separation liquid obtained by subjecting a dispersion liquid containing granular PAS to separation into granular PAS and a separation liquid; and a fine PAS powder.The method for manufacturing a fine PAS powder of the present invention includes: (a) separating granular PAS and a separation liquid from a dispersion liquid containing granular PAS, by solid-liquid separation using at least one screen that has an opening diameter of 75 to 180 μm; (b) performing solid-liquid separation of the separation liquid to obtain a fine PAS powder-containing solid; (c) heating the fine PAS powder-containing solid to reduce an amount of an organic solvent to obtain a wet cake; and (d) washing the wet cake using an aqueous solvent. The water content of the wet cake after heating is at least 30 wt. %.

Abstract: The techniques provide a system and a method of producing polyphenylene sulfide (PPS) polymer. The PPS polymer is produced by reacting a sulfur source and a dihaloaromatic compound in the presence of a polar organic compound in a polymerization mixture in a polymerization vessel. The PPS polymer is washed with a base to lower the oligomer content of the PPS polymer and thus the off-gassing during processing.

Abstract: Polyarylene sulfides are produced by polymerizing a dihalogen aromatic compound with an alkali metal hydrosulfide in the presence of a lithium halide in an organic polar solvent. In this polymerization, an alkali metal hydroxide and/or carbonate is added and a branching agent such as a trihalogen aromatic compound or a halogen aromatic nitro compound is used, if desired.The polyarylene sulfides have a high molecular weight and a less salt contents and a high degree of whiteness.
