Polyaryl sulfide resin composition and molded articles thereof

Abstract

This invention provides a polyarylene sulfide resin composition and a molded article thereof that exhibit excellent color stability, moldability, tensile strength, and nominal strain at tensile failure. The polyarylene sulfide resin composition of this invention comprises: (A) 100 parts by weight of a resin component formed from 30-85 parts by weight of a polyarylene sulfide resin (component A-1) satisfying formula (I) and 70-15 parts by weight of a polyarylene sulfide resin (component A-2) satisfying formula (II); (B) 1-10 parts by weight of an olefinic resin having functional groups that can react with component A; and (C) 0.1-5 parts by weight of a thermoplastic resin other than component A, whose cooling crystallization temperature is 160°C or higher. (In formulas (I) and (II), ΔL*, Δa*, and Δb* represent the values ​​obtained by subtracting L*, a*, and b* of a molded article injected at a cylinder temperature of 290°C from L*, a*, and b* of a molded article injected at a cylinder temperature of 300°C.)
