摘要： 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. %.

摘要： A poly(phenylene sulfide) fiber contains 1-10% by weight of a poly(phenylene sulfide) oligomer having a weight-average molecular weight of 5,000 or less, has a difference between a cold crystallization heat quantity (ΔHc) and a crystal melting heat quantity (ΔHm) during temperature rising in DSC, ΔHm−ΔHc, of 25 J/g or larger, and has an elongation of less than 40% and a strength of 3.0 cN/dtex or higher. The poly(phenylene sulfide) fiber has high heat resistance and chemical resistance and high strength and, despite this, has excellent suitability for high-order processing, e.g., thermal shapability, because the amorphous parts thereof have high molecular movability.

摘要： There is disclosed a process for treating a by-product salt from a polyarylene sulfide which comprises treating a solid mixture containing an aprotic organic solvent and the by-product salt that is formed in the case of producing the polyarylene sulfide by subjecting an alkali metal sulfide and a dihalogenated aromatic compound to polymerization condensation reaction in the aprotic organic solvent, characterized in that the aprotic organic solvent is recovered by dry treating the solid mixture by the use of a dryer having a self-cleaning property. It is enabled by the above process to efficiently recover the aprotic organic solvent, and thereby produce the objective polyarylene sulfide at a lower cost.
