This review focuses on the possible mechanisms of thermal or thermo-oxidative degradation of the copoly(ether-ester) elastomer (COPE) reported in formed literatures. The ester group, apart from the other functional groups, can occur in both hard and soft segments. The lifetime of the COPE is controlled by both oxidation and thermal degradation processes, which mostly proceed independently. The thermal oxidation of ester elastomers may occur during every stage of their life cycles during the synthesis, processing, storage or use of the final goods. The influences of the introduction of various additives on the processes of decomposition and aging of the COPE are compared. The proper choice of stabilizers and anti-oxidants, as well as initial substrates, caused the materials to endow them with excellent properties and high resistance to various environmental conditions.

这篇综述着重于现有文献中报道的共聚（醚酯）弹性体（COPE）热降解或热氧化降解的可能机理。除其他官能团外，酯基可以同时出现在硬链段和软链段中。COPE的寿命受氧化和热降解过程的控制，这些过程大多独立进行。酯弹性体的热氧化可能会在其最终产品的合成，加工，存储或使用过程中的生命周期的每个阶段发生。比较了各种添加剂的引入对COPE分解和老化过程的影响。正确选择稳定剂和抗氧化剂以及初始底物，
