The present invention refers to developing and obtaining new composite materials based on rubbers and/or elastomers and/or their recycled can be reused through an in situ polymerization program between the combination of different monomers and/or oligomers type diisocyanate, esters, or organic peroxides cross-linking agent, which in their combination generate a binding agent capable of modifying the intrinsic chemical, thermal, rheological, and mechanical properties in the material and the chains chemical cross-linking originated by the incorporation of organic peroxides which are able to accelerate or decrease the reaction rate.
