    Abstract: The present invention relates to a process for modifying the surface polarity of elastomeric rubber substrates to facilitate their cold bonding to other rubber substrates or non-elastomeric substrates of a different material, preferably metal, by chlorinating the rubber substrate surface by treatment with a chloride-containing composition and a peroxymonosulfate-containing composition. Further aspects relate to the thus obtained surface-modified rubber substrates, processes of bonding them to other substrates by use of an adhesives as well as the thus obtained bonded substrates.
