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.
新型 N,N'-双[(烷基羟基苯基)烷酰氧基羟基羰基]草酰胺可通过烷基羟基苯基烷酸、其酯或酸酐或相应的酸卤化物与 N,N'-双(羟基羟基羰基)草酰胺反应制备,可用作通常会氧化变质的有机材料的稳定剂,例如聚烯烃等聚合物。本发明提供了稳定受氧化劣化影响的有机材料的方法以及用 N,N'-双[烷基羟基苯基] 烷酰氧基羟基羰基]草酰胺稳定有机材料的方法。
