Abstract: A polyarylene sulfide resin composition obtained by melt-mixing a composition consisting essentially of 60 to 99 parts by weight of a polyarylene sulfide resin (component A), 1 to 40 parts by weight of a polyorgano-siloxane graft copolymer (component B) obtained by graft-polymerizing one or more kinds of vinyl monomer onto a compound rubber of 0.08 to 0.6 µm in average particle size consisting of a polyorganosiloxane rubber component and a polyalkyl (meth)acrylate rubber component and having such a structure that 1 to 99 wt.% of the polyorgano-siloxane rubber component and 1 to 99 wt.% of the polyalkyl (meth)acrylate rubber component have been inseparably united with each other, the total amount of the components A and B being 100 parts by weight, and an organic silane compound having an epoxy group (component C) of 0.01 to 10 parts by weight based on 100 parts by weight of the total amount of the components A and B. The composition of the present invention, whether it contains a reinforcing filler or not, is excellent in the compatibility between the polyarylene sulfide resin and polyorganosiloxane graft copolymer. If this composition is extrusion-molded or injection-molded under the common molding conditions, it keeps its original dispersed and mixed condition without showing a phase separation.      Consequently, this composition has excellent performances described below: Impact strength also is given to the polyarylene sulfide resin without largely injuring the excellent properties inherent in the resin; when this composition contains no reinforcing filler, there is no development of a pearly lustre which is easy to appear when the polyarylene sulfide resin and other resin component are mixed; and even when this composition contains a reinforcing filler, a molded product obtained therefrom is excellent in surface smoothness.
