causing oxidation of polar polymer systems; thereby prolonging the serviceability of a rubber article. Antioxidants also react with hydrocarbon radicals when they are formed. In doing so, antioxidants block the reaction sites that are available for the formation of peroxide and/or hydroperoxide radicals; thus retarding the oxidative process.
