A polyphenylene sulfide composition for use in injection molding is prepared by kneading a mixture comprising 100 parts by weight of a substantially linear polyphenylene sulfide which has been treated with an aqueous solution of an acid or of a salt of a strong acid and a weak base and of which not less than 70 mol% is composed of the repeating unit <CHEM> and 0.05 to 5 parts by weight of at least one aminoalkoxysilane compound, at a temperature higher than the melting point of said polyphenylene sulfide. |
