Abstract

Disclosed is a shaped resin article comprising (1) a continuous phase of a polyphenylene ether and (2) a dispersed phase dispersed in the continuous phase (1). The dispersed phase comprises (a) a particulate dispersed polyolefin phase which is comprised of a polyolefin and has a minor diameter of not greater than 0.5 .mu.m, the outer surface of the dispersed polyolefin phase (a) having, cohered thereto, particles of at least one copolymer selected from the group consisting of a copolymer of a vinyl aromatic compound and a conjugated diene compound and a hydrogenation product thereof, and (b) a particulate dispersed copolymer phase having a minor diameter of not greater than 0.3 .mu.m, which is comprised of at least one copolymer selected from the above-mentioned group and is dispersed in the continuous phase (1) and not cohered to the dispersed polyolefin phase (a). The shaped resin article has not only remarkably improved weld-line toughness and delamination resistance but also excellent resistance to heat, impact and chemicals.
