ABSTRACT:
A polyarylene sulfide resin composition comprising a resin composition obtainable by polymerizing 40 to 0.1 part by weight of an unsaturated polyester and 0.01 to 30 parts by weight of a monomer having one or more ethylenic unsaturated bonds in the presence of 100 parts by weight of a composition comprising 1 to 99 wt. % of a polyarylene sulfide resin and 99 to 1 wt. % of a thermoplastic polyester. Since the polyarylene sulfide resin composition of the present invention is in a state wherein the polyarylene sulfide resin and thermoplastic polyester are uniformly mixed, the constituent components are uniformly dispersed and mixed to such a degree that the composition shows no phase separation even if it is passed through molding processes such as extrusion molding, injection molding, etc. carried out under normal conditions. Consequently, the composition of the present invention is very superior in that the adhesive property of paint film (paintability), which the conventional polyarylene sulfide resins do not have well, has been improved without a large reduction in the excellent properties of the polyarylene sulfide resin.
