Zusammenfassung:Additives for rubber compositions, giving vulcanisates having improved retention of optimum physical properties, are compounds containing two or more groups of the formula -S-SO2R linked by an organic bridging group, or polymers containing two or more groups of the formula -S-SO2R attached to an organic polymer chain, where R represents (a) a radical OM where M is a monovalent metal, the equivalent of a multivalent metal, a monovalent ion derived by the addition of a proton to a nitrogenous base, or the equivalent of a multivalent ion derived by the addition of two or more protons to a nitrogenous base, or (b) an organic radical selected from aliphatic, cycloaliphatic, aromatic and heterocyclic radicals, and radicals which are combinations of any two or more such radicals.
