Beschreibung
Zusammenfassung:	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.
