Abstract: Novel and long-acting rubber anti-degradant and rubber composition comprising the same for tires. The anti-degradant comprises at least two compounds, each of which is selected from a compound of Formula I, II, III-a, or III-b: and each of the compounds have different formulae from others, and can't be compounds of formula III-a and III-b at the same time when the anti-degradant consists of only 2 compounds. The anti-degradant is used to provide a rubber composition with improved long-term resistance to thermo-oxidative aging and ozone aging.

Abstract: A formulation for rubber composition with reduced odor and good thermal oxidative aging-resistance and tension fatigue resistance comprising 100 parts by weight of a diene elastomer, 30 to 70 parts by weight of a reinforcing filler, 0.1 to 8 parts by weight of an antidegradant composition, and 0.5 to 3 parts by weight of a crosslinker, wherein the antidegradant composition includes a 6PPD antidegradant with a purity of equal to or greater than about 98% and an S-TMQ. The rubber composition has no added odor inhibitor/adsorbent or deodorizing additive, while by using combination of 6PPD with purity of equal to or greater than about 98% and an S-TMQ instead of traditional combination of 6PPD and a TMQ, the VOC emission of the rubber composition is effectively reduced, the odor grade is reduced, and the thermal oxidative aging-resistance and tension fatigue resistance is improved.
