Abstract
An antidegradant composition, an antidegradant master batch comprising the antidegradant composition and a rubber composition comprising the antidegradant composition or the antidegradant master batch. The antidegradant composition comprises antidegradant TMPPD and one or two selected from antidegradant N3100-B and an antidegradant N3100-C. The antidegradant composition and antidegradant master batch render a rubber compound and a rubber article excellent discoloration resistance, fatigue resistance, ozone resistance, and mechanical properties before and after thermal oxidative aging and enables the rubber compound to be used in the manufacture of all or part of the rubber matrix, especially as a tire sidewall rubber composition and a tire tread rubber composition.
