  Thermoplastic copolyetherester elastomers are stabilized against heat and light aging by incorporating into the , copolyetherester effective concentrations of a phenolic antioxidant and a hindered amine photostabilizer of the formula where R is hydrogen or an alkyl radical of 1-12 carbon atoms, R2 and R3 are alkyl radicals of 1-12 carbon atoms, benzyl, or 3,5-di-tert-butyl-4-hydroxybenzyl.

  在热塑性共聚醚酯中加入有效浓度的酚类抗氧化剂和受阻胺光稳定剂，可稳定热塑性共聚醚酯弹性体，防止热老化和光老化。 其中 R 是氢或 1-12 个碳原子的烷基，R2 和 R3 是 1-12 个碳原子的烷基、苄基或 3,5-二叔丁基-4-羟基苄基。
