  A composition of matter is disclosed wherein the composition comprises an N-aromatic substituted acid amide compound selected from the group consisting of compounds of formula (I) wherein A and B are independently selected alkylene groups; R 1 is selected form the group consisting of hydrogen, alkyl alkylether, or ester; R 2 is hydrogen if R 1 is hydrogen; R 2 is an alkyl primary amine if R 1 is alkyl, alkylether, or ester, R 3 and R 4 are independently selected from the group consisting of hydrogen and alkyl; R 5 is a sterically hindered phenolic group of formula (II) or formula (III) wherein X is CH 2 , S, NH, or O; and m, n, and p are independently selected integers equal to 0 or 1. These compositions may be used as such or they may be bound to a polymer backbone via a linking moiety. In either case, they are useful as antioxidants, particularly in lubricating oil compositions.
