“…Such reasoning, however, cannot explain the inhibiting action of carbon black in unvulcanized cold rubber which contains antioxidant. In this system previously described in detail (7), increasing the carbon black loading decreases the rate of oxidation. Kuz'minskii's theory predicts that increasing the carbon black loading would increase the oxidation rate.…”

“…For a number of years it has been apparent that carbon black can act as an inhibitor as well as an accelerator of rubber oxidation. On the one hand work in this laboratory showed that carbon black is a strong inhibitor of unvulcanized cold rubber oxidation (7,70). On the other hand several investigators have demonstrated that carbon black accelerates the oxidation of rubber vulcanizates (2,73).…”

“…Since excellent carbon black vulcanizates can be prepared xvith dicumyl peroxide as the curative (7), this wras the first nonsulfur system studied. The effect of carbon black loading on the oxygen absorption of dicumyl peroxide-GR-S vulcanizates is presented in Figure 2.…”

Carbon black can function as an inhibitor or as an accelerator of oxidation and cure of rubber as well as of other polymers.The inhibiting action of carbon black on the oxidation of unvulcanized cold rubber appears to be related to, if not the cause of, the increased reinforcement of the heat-treated stock. In general, the effect of carbon black on the oxidation of cold rubber and natural rubber is the same.With a more complete understanding of the role of carbon black in polymer oxidation and cure reactions, it should be possible to control the behavior of carbon black so that advantage can be taken of its inhibiting and accelerating properties in prolonging the life and increasing the usefulness of rubber goods.

“…Hence, the effect of carbon black on oxidation was termed to be a catalytic one. Much information on the effect of carbon black upon the oxidation of rubber has been reported by other laboratories. Sweitzer and coworkers have observed an inhibitory effect (6,11,19). Kuz'minskii and his group found an acceleration, but explained it on a different basis (10).…”
