Abstract
Abstract A highly heat resistant thermoplastic resin composition having high oil-resistance containing (a) polyphenylene ether resin (b) a copolymer comprising units of a vinyl aromatic compound and either an α,β - unsaturated dicarboxylic acid anhydride or an imide compound thereof, and (c) a polyamide, and optionally if desired (d) an impact-resistant-reinforcing agent. To suit molded articles, this composition may be blended with a polymer containing a vinyl aromatic compound, phosphorous-containing compounds, or glass or carbon fibers. Articles are molded from the compositions by conventional means.
