56 ABSTRACT OF THE DISCLOSURE Disclosed is a shaped resin article comprising (1) a continuous phase of a polyphenylene ether and (2) a dis- persed 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 µm, the outer surface of the dispersed polyolefin phase (a) having, cohered thereto, particles of at least one copolymer se- lected 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 dis- persed copolymer phase having a minor diameter of not greater than 0.3 µm, 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 tough- ness and delamination resistance but also excellent resist- ance to heat, impact and chemicals.
