Polymeric antioxidants prepared from diphenyalmine and dialkylalkenylbenzene or dihydroxyalkylbenzene

摘要

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 acrylonitrilebutadiene and styrene-butadiene rubbers to protect these rubbers in high temperature, oxidative working environments.
