Abstract:
1. A shaped resin article comprising: a polyamide (A) comprising at least two different polyamide components, a polyphenylene ether (B), one or more partially hydrogenated block copolymers (C), each independently obtained by partially hydrogenating an unhydrogenated block copolymer comprising at least one aromatic vinyl polymer block comprised mainly of aromatic vinyl monomer units, and at least one conjugated diene polymer block comprised mainly of conjugated diene monomer units, said partially hydrogenated block copolymers (C) including at least one partially hydrogenated block copolymer (C-1) having a number average molecular weight of from 200,000 to 300,000, and wollastonite particles (E) having an average particle diameter of from 2 to 9 μm, wherein said polyamide (A) is present as a continuous phase in which said polyphenylene ether (B) is dispersed to form a dispersed phase, and said partially hydrogenated block copolymer (C) is present in at least one phase selected from the group consisting of said continuous phase of the polyamide (A) and said dispersed phase of the polyphenylene ether (B), wherein said polyamide (A) is exposed on a surface of said shaped resin article so that the surface area of the polyamide (A) exposed on the overall surface of said shaped resin article is at least 80%, based on the surface area of the shaped resin article, wherein said polyphenylene ether (B) contains relatively high molecular weight polyphenylene ether molecules, each independently having a molecular weight of 200,000 or more, and relatively low molecular weight polyphenylene ether molecules, each independently having a molecular weight of 5,000 or less, wherein the weight ratio of said relatively high molecular weight polyphenylene ether molecules to said relatively low molecular weight polyphenylene ether molecules is 0.35 or less, and the amount of said relatively low molecular weight polyphenylene ether molecules and the amount of said relatively high polyphenylene ether molecules are, respectively, 5% by weight or less and 2% by weight or less, based on the weight of said polyphenylene ether resin (B).
