POLYARYLENE SULFIDE RESIN COMPOSITION AND INSERT-MOLDED ARTICLE

摘要

Provided is a PAS resin composition with which molded articles having excellent high- and low-temperature impact properties can be obtained and which can be highly inhibited from leaving mold deposits when molded and is suitable for use in insert molding. Also provided is an insert-molded article obtained using the resin composition. The PAS resin composition comprises a PAS resin having terminal carboxy groups and an olefin copolymer, wherein the olefin copolymer comprises units of an a-olefin, the glycidyl ester of an a,ß-unsaturated acid, and an acrylic ester as comonomer units, the PAS resin has a number-average molecular weight of 1,000-10,000, and the content of the comonomer units derived from the glycidyl ester in the resin composition is 0.08-0.20 mass%, the ratio of the amount of the terminal carboxy groups (mmol/kg) and the content of the comonomer units derived from the glycidyl ester (mmol/kg) being 0.35-1.00.
