ABSTRACT:
This invention relates to a novel class of polymeric compositions which have molecular weights ranging from 300 to 9000 and are the reaction product of (a) an alkyl or cycloalkyl substituted diphenyldiamine and (b) a vinyl ether. The polymeric diphenyldiamine compounds are useful as an antiozonant in diene containing polymers and surprisingly accelerate the rate of cure of the diene containing polymers.
