Product based on rubber, such as a tyre, and process for reducing the rolling resistance of the said tyre

摘要

Rubber-based product with a buffer zone comprising an elastomer and an oxidation activator for trapping external oxygen and protecting a sensitive zone from oxidation, comprises a ferric salt of an aromatic monocarboxylic acid (I) as the oxidation activator. ??Rubber-based product with a buffer zone comprising an elastomer and an oxidation activator for trapping external oxygen and protecting a sensitive zone from oxidation, comprises a ferric salt of an aromatic monocarboxylic acid of formula (I) as the oxidation activator. ??Ar-COOH (I) ??Ar = phenyl optionally substituted by 1-5 of 1-8C alkyl (optionally substituted), alkoxy or CN or fused with one or more optionally substituted 6-10C aryl groups.
