    • A rubber composition comprising the following compound: R1—NH-phenyl-NH—R2 where the amino moieties occupy the 1 and 4 positions of the phenyl ring, and R1 and R2 are selected from the group consisting of H, C1 to C3 straight chain or branched alkyl groups, and wherein R1 and R2 may be the same or different; and where the t90, isothermal at 125° C. is within thirty percent of the t90, after 28 days aging at forty degrees Celsius (40° C.), as the unaged green rubber composition. In another embodiment, R1 and R2 are selected from C4 to C5 straight chain or branched alkyl groups. In another embodiment of the invention, R1 and R2 are selected from C6 to C15 straight chain or branched alkyl groups. In another embodiment of the invention, the rubber compound is greater than 5 parts by weight per hundred parts of the rubber composition.
