Abstract

Compositions comprising new halogenated butyl rubbers with a defined, low content of halogen, a defined content of non-halogenated double bonds and a defined content of anti-agglomeration/vulcanisation control agents and containing polymer compounds comprising special amidines, mercapto or zinc mercapto compounds and polymers possess outstanding mechanical and physiological properties, so that they are suitable for the production of tyres, particularly tyre inner liners, tyre sidewalls and tyre treads.
