Abstract
A polyarylene sulfide resin composition is improved in mold releasing characteristics in molding, is thermally and chemically stable, evolves little decomposition gases and exhibits excellent mechanical characteristics. The composition can be prepared by blending (A) 100 parts by weight of a polyarylene sulfide resin with (B) 0.01 to 5 parts by weight of an ester compound composed of a polybasic aliphatic carboxylic acid and a monohydric aliphatic alcohol.
