Abstract
Unvulcanized or partially vulcanized rubber is coated with a coating poly capable of co-vulcanizing with the rubber and having functional groups capable of reacting with an adhesive. The coated rubber is then subjected to vulcanizing conditions. When the treated rubber surface is bonded to an adhesive, the functional groups react with the adhesive forming strong bonds.
