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.
热塑性树脂组合物包括热塑性树脂或其混合物、一定量的稳定剂或稳定剂混合物(选自酚类抗氧化剂、3-芳基苯并呋喃酮、受阻胺稳定剂、紫外线吸收剂、有机磷化合物、脂肪酸的碱金属盐、羟胺和硫代增效剂)以及一定量的氧化叔胺。由于同时存在有效量的氧化叔胺,这些组合物在暴露于加热或天然气燃烧产物时的变色稳定性得到提高。
