Thermoplastic resin composition are provided that comprise a thermoplastic resin or mixture thereof, a stabilizing amount of a stabilizer or mixture of stabilizers selected from the group consisting of the phenolic antioxidants, the 3-arylbenzofuranones, the hindered amine stabilizers, the ultraviolet light absorbers, the organic phosphorus compounds, the alkaline metal salts of fatty acids, the hydroxylamines, and the thiosynergists, and a stabilizing amount of a tertiary amine oxide. The compositions have improved stability against discoloration upon exposure to heating or to the combustion products of natural gas by the concomitant presence of an effective amount of a tertiary amine oxide.
