المستخلص : Four compounds of diphenylamine derivatives were prepared and evaluated as thermal stabilizers and antifatigue agents in natural rubber (NR) mixes. The efficiencies of these compounds were compared with phenyl-B-naphthylamine, which is widely used in rubber industry. The rheological characteristics were determined using an oscillating disc rheometer. The physico-mechanical properties of the rubber vulcanizates were measured before and after exposure to accelerated thermooxidative ageing. The results revealed that the prepared compounds were good antioxidants and antifatigue agents for rubber vulcanizates. In addition, it was found that the chemical structure of the compounds has a great effect on their efficiency as stabilizers, that is, the presence of electron donating group increases their efficiency, whereas the presence of electron withdrawing group decreases it.
