Copper salts of aryl amine-substituted carboxylic anhydride derivatives are prepared by reacting a long chain carboxylic acid, carboxylic anhydride or carboxylic acid-forming compound having from about 30 to 200 carbon atoms with a secondary aryl amine, and reacting the resultant intermediate with a copper salt to obtain the final reaction product. The reaction product may be used as an additive to a lubricant to improve the antioxidant properties thereof.
