  A process for preparing a polyarylene sulfide involves contacting a sulfur source with a metallic salt of ω -hydroxycarboxylic acid and a dihalogen aromatic compound in an organic polar solvent, thereby carrying out polycondensation with stability in a polymerization system in which a water content is large. The polyarylene sulfide prepared has a high degree of whiteness and with a sufficiently high molecular weight. The use of the metallic salt of ω -hydroxycarboxylic acid in a particular range can provide a novel polyarylene sulfide.

  A polyarylene sulfide has an inherent viscosity [η inh] of 0.1 to 0.5 dl/g, a weight-average molecular weight of 1 x 10⁴ to 2 x 10⁵; a ratio of the inherent viscosity [ η inh] to a calculated viscosity [η]calc ([η inh]/[η ]calc ) of 0.4/1 to 0.8/1; and a degree of whiteness of 50 or higher when measured in accordance with whiteness testing procedures (JIS P8123). The polyarylene sulfide is prepared by reaction by contacting at least one member of a metallic sulfide (A) selected from an alkali metal sulfide and an alkali metal hydrosulfide with a dihalogen aromatic compound (B) and an aromatic compound (C) having three or more than three functional groups in a polar solvent in a molar ratio of the dihalogen aromatic compound (B) to the metallic sulfide (A) [(B)/(A)] ranging from 1.035/1 to 1.300/1 and in a molar ratio of the aromatic compound (C) to the dihalogen aromatic compound (B) [(C)/(B)] ranging from 0.003/1 to 0.05/1.
