Abstract
An organoclay-antiozonant complex suitable for incorporating in rubber formulations as an additive to inhibit and retard ozone attack is formed by complexing a substituted paraphenylenediamine antiozonant with an organoclay having been produced by treating a smectite-containing clay with a quaternary amine. The organoclay-antiozonant complex is preferably incorporated into the rubber formulation by first mixing the prepared organoclay-antiozonant complex with a naphthenic oil and a polar solvent to form a paste which is then added to the rubber formulation.
