2. Description of the Related Art Polyphenylene sulfide (hereinafter referred to as PP
Polyarylene sulfide (hereinafter abbreviated as PAS) resin represented by S) has excellent heat resistance and chemical resistance in itself, and is a molding material reinforced with a reinforcing material such as glass fiber among others. Is being used as a metal substitute in the fields of automobile parts, electronics-related parts, etc., and in recent years the demand has greatly increased.

However, unreinforced PAS resin which is not reinforced with a reinforcing material such as glass fiber is inferior in extrusion stability and moldability, and the obtained molded product is not only black in appearance but also poor in impact resistance. , The mechanical properties such as tensile elongation are insufficient, and the toughness is not obtained. Therefore, in the field of injection molding, its use is restricted as a non-reinforcing molding material, and a reinforced PAS resin using a reinforcing material has been mainly used.

By the way, as a method for improving the toughness of a PAS resin represented by PPS, a method of adding a hydrogenated SBR copolymer (JP-A-59-167040) and a dicarboxylic acid anhydride hydrogenated SBR copolymer are used. However, these SBR copolymers have poor compatibility with PAS resins, poor appearance, and impact resistance is not sufficiently improved. Further, addition of an ionomer (JP-A-2-490
No. 62), the heat resistance of the ionomer is poor, and burns easily occur during molding. Furthermore, the addition of a copolymer consisting of a glycidyl ester of an α-olefin and an α, β-unsaturated carboxylic acid (JP-A-58-154757), a glycidyl ester of an α-olefin and an α, β-unsaturated carboxylic acid Addition of a copolymer obtained by graft-polymerizing a vinyl-based monomer to the copolymer (JP-A-1-198664), a copolymer of α-olefin, an α, β-unsaturated carboxylic acid alkyl ester and maleic anhydride. Addition (JP-A-62-
No. 151460) are also known. However, the impact resistance and tensile elongation have not been sufficiently improved even by the addition of these copolymers. In addition, if a large amount of the above-mentioned copolymer consisting of α-olefin and glycidyl ester of α, β-unsaturated carboxylic acid is added to PAS resin, PA
The S resin was in the form of gel and its amount used was limited. Further, the addition of the above-mentioned copolymer containing maleic anhydride did not cause gelation, but the compatibility was deteriorated, and the amount used was also small.
