Abstract of the Disclosure POLYMERIC ANTIOXIDANTS PREPARED FROM DIPHENYLAMINE AND DIALKYLALKENYLBENZENE OR DIHYDROXYALKYLBENZENE A class of novel polymeric diphenylamine compounds are used to provide antioxidant protection to oxidizable polymers. In particular, the polymeric reaction products of diphenylamine and 1,4- diisopropenylbenzene are used in acrylonitrile- butadiene and styrene-butadiene rubbers to protect these rubbers in high temperature, oxidative working environments.
