Novel N,N'-bis [(alkylhydroxyphenyl) alkanoyloxyhydrocarbyl] oxamides which can be prepared by reacting an alkylhydroxyphenylalkanoic acid, an ester or anhydride thereof or a corresponding acid halide with an N,N'- bis(hydroxyhydrocarbyl) oxamide, are useful as stabilizers of organic materials normally subject to oxidative deterioration, e.g. polymers such as polyolefins. Methods of stabilizing organic materials subject to oxidative deterioration and stabilized organic materials with N,N'-bis [alkylhydroxyphenyl) alkanoyloxyhydrocarbyl] oxamides are provided.
