    摘要: The present invention relates to a heat resistant molding resin composition comprising 60-99.9% by weight of an aromatic polyamideimide resin, and 40-0.1% by weight of a thermoplastic resin which comprises at least one member selected from the group consisting of a polyphenylene sulfide resin, a polyamide resin, a polysulfone resin, an aromatic polyester resin, a polyphenylene-ether resin and a phenoxy resin. The thermoplastic resin must have a melt viscosity at 350.degree. C. of not more than 1.times.10.sup.5 poise and a decomposition temperature of not lower than 350.degree. C. The aromatic polyamideimide resin is improved in melt viscosity characteristics by being blended with the thermoplastic resin. Therefore, a resin composition is obtained which is excellent in moldability characteristics. This composition may optionally comprise various kinds of fillers. Shaped articles, obtained by melt molding of the compositions in accordance with the present invention, are excellent in heat resistance, mechanical characteristics, electrical characteristics, sliding characteristics and solvent resistance characteristics and may be utilized in many different ways.
