NOVELTY - A rubber composition comprises a diene elastomer, a reinforcing filler, a vulcanization system, and an antidegradant comprising an amide-containing compound (I). USE - Rubber composition used for forming rubber article e.g. tire (claimed) e.g. pneumatic tire, solid tire, non-pneumatic tire, and belt, hose, cable, automotive mount, bushing and general mechanical product. ADVANTAGE - The rubber composition has improved antiozonation performance. DETAILED DESCRIPTION - A rubber composition comprises a diene elastomer, a reinforcing filler, a vulcanization system, and an antidegradant comprising an amide-containing compound of formula (I). m = 1 or 2; n = 0, 1, or 2; p = 0, 1, 2, 3, or 4; q = 0, 1 , 2, 3, or 4; R',R'' = alkyl, cycloalkyl, aryl, amino, amido, alcohol moiety, aldehyde moiety, keto, carboxylic acid moiety, ether, ester, or thio;and R1,R2 = H, or R'.
