Abstract
Disclosed herein is a thermoplastic resin composition which comprises: PA1 (a) a polyphenylene ether resin or a polyphenylene ether-containing resin composition, PA1 (b) a polypropylene grafted with a styrene-based monomer and/or a propylene copolymer grafted with a styrene-based monomer, PA1 (c) an ethylene-.alpha.-olefin copolymer grafted with a styrene-based monomer, said ethylene-.alpha.-olefin copolymer having a density of 0.85-0.91 g/cm.sup.3 and a maximum melting peak temperature of 100.degree. C. and above measured with a differential scanning calorimeter (DSC), and PA1 (d) optionally, rubbery substance. Also disclosed herein is a process for producing a thermoplastic resin composition which comprises incorporating a preblend composed of: PA2 (a') a polyphenylene ether resin or a polyphenylene ether-containing resin composition, PA2 (b') a polypropylene and/or a propylene copolymer, PA2 (c') an ethylene-.alpha.-olefin copolymer having a density of 0.85-0.91 g/cm.sup.3 and a maximum melting peak temperature of 100.degree. C. and above measured with a differential scanning calorimeter (DSC), and PA2 (d') optionally, a rubbery substance with a styrene-based monomer and an orga…
