This invention relates to a novel class of polymeric compositions which have molecular weights ranging from 300 to 10,000 and are the reaction product of (a) an N-aryl or N-alkaryl substituted diphenyldiamine and (b) a conjugated or nonconjugated diene. These polymeric N-aryl substituted and N- alkaryl diphenyldiamine compounds are particularly useful as an antioxidant in diene containing polymers.
