ABSTRACT:
Reversion resistance of a sulfur cured aircraft carcass rubber compound is greatly improved by incorporating, as anti-reversion agents, 1.5-6 phr of a mixture of zinc salts of one or more C.sub.8 -C.sub.10 aliphatic carboxylic acids and one or more monocyclic aromatic acids, and 0.8-2 phr of a bis-citraconimido compound. Much greater reversion resistance is obtained with a combination of the two anti-reversion agents than with either anti-reversion agent alone.
