Abstract: An antioxidant polymer (e.g., oligomer) composition comprising repeat units of lylamine monomers of formula I wherein R is H, C 1 -C 18 alkyl, C 2 -C 18 alkenyl, C 2 -C 18 alkynyl, -C(O)C 1 -C 18 alkyl, -C(O)aryl and R 1 , R 2 , R 3 and R 4 are each independently H or a linear or branched C 1 -C 18 alkyl, C 1 -C 18 alkoxy, C 1 -C 18 alkylamino, C 1 -C 18 dialkylamino, C 1 -C 18 alkylthio, C 2 -C 18 alkenyl, C 2 -C 18 alkynyl or C 7 -C 21 aralkyl and wherein the number average molecular weight (Mn) of the polymer is from about 350 g/mol to about 5000 g/mol are highly effective antioxidants in lubricant compositions. The polymer compositions may be prepared by a process comprising subjecting diarylamine monomers to dehydrocondensation conditions.
