ABSTRACT:
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.
