Abstract
This invention relates to a novel class of polymeric compositions which have molecular weights ranging from 300 to 3000 and are the reaction product of (a) an alkyl or cycloalkyl substituted diphenyldiamine and (b) a conjugated or nonconjugated diene. The polymeric diphenyldiamine compounds are particularly useful as an antiozonant in diene containing polymers.
