The present invention is directed to the functionalization of butyl rubber ionomer and optionally the grafting of polyamide to halobutyl rubber ionomers. Specifically, disclosed are methods and products resulting therefrom for creating functionalized ionomers and grafting polyamide to halobutyl ionomers via reactive extrusion. The process comprises reacting a halobutyl polymer with at least one nitrogen and/or phosphorous based nucleophile to provide a halobutyl ionomer comprising conjugated diene units; grafting of an amine-reactive dienophile to said ionomer to form a functionalized ionomer; and optionally blending the resulting functionalized ionomer with polyamide.

A rubber coating layer is prepared from a sprayable aqueous coating dispersion including: a rubber dispersion including a rubber binder dispersed in an aqueous medium, a sulfur-containing vulcanization agent, and a platy inorganic material. The coating dispersion or a film formed from the coating dispersion is vulcanized at a temperature of from 100° C. to less than 160° C. for up to 1 hour to form the rubber coating layer having a melt temperature of greater than 60° C. A sprayable pre-vulcanized coating dispersion is prepared from a coating dispersion including: a rubber dispersion comprising a rubber binder dispersed in an aqueous medium, a sulfur-containing vulcanization agent, and a platy inorganic material. The coating dispersion is vulcanized at a temperature of from 70° C. to less than the boiling point of the aqueous medium to form the pre-vulcanized coating dispersion.

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 elastomeric 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 adhesive, as well as the thus-obtained bonded substrates.
