Abstract: There are provided polymer stabilizers having the formula
wherein
A is an organic tetravalent radical of 2 to 48 carbons,
D is a divalent radical -C(=O)-N(G)-C(=O)-(CH₂) x -, where x is 0 or 1,
E is a monovalent radical -(CH₂) x -C(=O)NH-G, where x is 0 or 1,
d is 0, 1 or 2 and
G is the residue of a stabilizer group, e.g., a hydrazido-substituted hindered phenol or a hydrazido-­substituted hindered amine light stabilizers
The polymer stabilizers are prepared by the reaction of hydrazido-substituted or certain amino-substituted polymer stabilizers and cyclic dianhydrides. The polymer stabilizers of the invention are useful for protecting a large variety of synthetic polymeric organic materials from the degradative effects of heat, light and oxygen. Some of the modifiers are flame retardants and many more metal deactivators in addition to their primary activity.

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.
