ABSTRACT OF THE DISCLOSURE Disclosed herein is a polyarylene thioether composition comprising: 100 parts by weight of a polyarylene thioether (A) which contains not less than 70 wt% of a repeating unit of Image ; and 0.01 to 15 parts by weight of a polyarylene thioether (B), which is a nucleating agent and contains not less than 60 wt% of a repeating unit of Image as the main constituent and has a melting point of not lower than 290°C or a melt crystallizationtemperature of not lower than 220°C. This composition may further comprise 0.1 to 300 part by weight of an inorganic filler and/or a fibrous filler. A 50% crystallization time,?1/2, at 250°C of the polyarylene thioether composition is not more than 1/1.5 of the 60% crystallization time of a polyarylene thioether whichdoes not contain the polyarylene thioether (B) Accordingly, its melt molding cycle is short and its molded product has a high strength.
