Polyarylene sulfide resin is an engineering plastic with excellent chemical resistance, heat resistance, mechanical properties, etc. For this reason, polyarylene sulfide resins are widely used as electrical and electronic parts, vehicle-related parts, aircraft parts, and housing equipment parts. However, the polyarylene sulfide resin has a problem that burrs are generated during molding. As a means for solving this problem, Patent Document 1 discloses a resin composition containing a polyphenylene sulfide resin and a polycarbonate resin. However, since the conventionally commercially available polyphenylene sulfide resin contains a certain amount of sodium as an impurity due to the limitation of the polymer polymerization method, the polycarbonate resin is remarkably decomposed during the molding process to exhibit excellent properties. Not reached. Patent Document 2 proposes a polyphenylene sulfide resin having a reduced chlorine content. However, the decomposition of the polycarbonate resin cannot be suppressed only by using the polyphenylene sulfide resin having a reduced chlorine content. Further, in order to reduce the chlorine content, the reaction process becomes complicated and the cost competitiveness is inferior. Patent Document 3 discloses a polyphenylene sulfide resin in which an alkali metal is reduced, but it is not intended to be modified with a polycarbonate resin and is inferior in cost competitiveness. Patent Document 4 discloses a resin composition containing a polyphenylene sulfide resin and a thermoplastic resin having a dispersity of 2.5 or less and an alkali metal content of 50 ppm or less. However, it was not intended to be modified with a polycarbonate resin, particularly to suppress burrs, and its characteristics were not satisfactory. Further, Patent Document 5 discloses a resin composition composed of a polyphenylene sulfide resin and a polycarbonate resin containing a branched structure, and Patent Document 6 discloses a resin composition containing a polyphenylene sulfide resin and a polycarbonate resin in which decomposition of the polycarbonate resin is suppressed. However, the mechanical strength and heat resistance of the resin composition were insufficient.
