Abstract: A lubricant composition includes a base oil present in an amount of greater than 70 parts by weight per 100 parts by weight of the lubricant composition and an antioxidant. The antioxidant has the structure: wherein each X is independently CH or N, so long as at least one X is N. A is an electron donating group that (1) has an atom having at least one lone pair of electrons that is bonded directly to the aromatic ring or (2) is an aryl or alkyl group. Z is chosen from a hydrogen atom and an electron donating group that has an atom having at least one lone pair electrons that is bonded directly to the aromatic ring or is an aryl or alkyl group.

Abstract: A lubricant composition includes a base oil present in an amount of greater than 70 parts by weight per 100 parts by weight of the lubricant composition and an antioxidant. The antioxidant has the structure: wherein each X is independently C-A or N, so long as at least one X is N but no more than two of X are N. Moreover, A is H, cyano or an electron donating group that: (1) has an atom having at least one lone pair of electrons that is bonded directly to the aromatic ring; or (2) is an aryl group or alkyl group. Further, each R is independently H, an alkyl group, or aryl group and each R′ is independently an alkyl group or an aryl group.

Abstract: A lubricant composition includes a base oil present in an amount of greater than 70 parts by weight per 100 parts by weight of the lubricant composition and an antioxidant. The antioxidant has the structure: wherein each X is independently CH or N, so long as at least one X is N, wherein Y is CRR′, NR″, PR″, S, or O, each R, R′ and R″ is independently H, alkyl or aryl, and R″ is alkyl, aryl, alkoxy or aryloxy. Each A is independently an electron donating group. The electron donating group (1) has an atom having at least one lone pair of electrons that is bonded directly to the aromatic ring, (2) is an aryl or alkyl group, or (3) is a hydrogen atom.

Abstract: An antioxidant polymer (e.g., oligomer) composition comprising repeat units of diphenylamine monomers of formula I wherein R is H, C1-C18 alkyl, C2-C18 alkenyl, C2-C18 alkynyl, —C(O)C1-C18 alkyl, —C(O)aryl and R1, R2, R3 and R4 are each independently H or a linear or branched C1-C18 alkyl, C1-C18 alkoxy, C1-C18 alkylamino, C1-C18 dialkylamino, C1-C18 alkylthio, C2-C18 alkenyl, C2-C18 alkynyl or C7-C21 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.
