Phenolic N-(amido)imides are provided which are useful as antioxidant stabilizers for organic materials, including a large variety of synthetic polymers, typically subject to thermooxidative degradation. The antioxidant effectiveness of the phenolic N-(amido)imide stabilizers is enhanced by the deactivating potential of the amido-imide moiety towards metals or metal ions that frequently contaminate polymer compositions and serve to catalyze thermal degradation.
本发明提供的酚类 N-(氨基)酰亚胺可用作有机材料的抗氧化稳定剂,其中包括各种通常会发生热氧化降解的合成聚合物。酚类 N-(氨基)酰亚胺稳定剂的抗氧化效果因氨基-酰亚胺分子对金属或金属离子的失活潜能而得到增强,这些金属或金属离子经常污染聚合物成分并催化热降解。
