ABSTRACT:
A polyphenylene ether resin composition containing (A) 100 parts by weight of a polyphenylene-ether-base resin composed of 100-60 wt. % of a polyphenylene ether resin and 0-40 wt. % of a polystyrene resin and (B) 1-40 parts by weight of a dicarboxylic acid ester copolymer obtained from a vinyl monomer and an unsaturated dicarboxylic acid ester as copolymerizable components. The dicarboxylic acid ester copolymer has a weight average molecular weight not greater than 60,000. The polyphenylene ether resin composition, if necessary, can further comprise (C) 1-40 parts by weight of conductive carbon or an A-B-A' type or A-B'-B" type block copolymer elastomer. Owing to its excellent mechanical properties, heat resistance and moldability, the resin composition is useful in the fields of automotive vehicles, home electronic or electric appliances and industrial parts or components.
