ABSTRACT OF THE DISCLOSURE A polyarylene sulfide resin composition obtainable by mixing (A) 99 to 60 parts by weight of a polyarylene sulfide resin, (B) 1 to 40 parts by weight of a polyorgano- siloxane rubber, in which 0.1 to 20 wt.% of a siloxane compound represented by the following formula (I): HS(CH2)p-SiRn(OR')3-n (I) wherein R represents a methyl, ethyl, propyl or phenyl group, R' represents a methyl or ethyl group, n represents an integer of 0, 1 or 2, and p represents an integer of 1 to 6, are copolymerized, having an average particle size of 0.1 to 0.5 µm and a degree of swelling of 3 to 50 measured by immersing in toluene, or a polyorganosiloxane graft copolymer prepared by graft- polymerizing a monomer comprising at least one of an unsaturated carboxylic acid and its anhydride to a polyorganosiloxane rubber having an average particle size of 0.1 to 0.5 µm and a degree of swelling of 3 to 50 measured by immersing in toluene, (C) 0.01 to 10 parts by weight, based on 100 parts by weight of the total weight of the components (A) and (B), of at least one polyfunctional compound selected from the group consisting of polyfunctional isocyanate compounds, polyfunctional oxazoline compounds and polyfunctional epoxy compounds, and (D) 0 to 300 wt.%, based on the total weight of the components (A), (B) and (C), of a filler, and then reacting these components. The composition of the present invention is an excellent composition having excellent impact resistance without a large reduction in the excellent performances inherent to a polyarylene sulfide resin such as heat resistance, mechanical strength, etc.
