Abstract
A process for making a thermoplastic vulcanizate includes blending a thermoplastic first polymer, an elastomeric second polymer, a carboxylic anhydride, a free radical generator, and a tackifier to provide a tacky first blend containing the thermoplastic first polymer and grafted elastomeric second polymer with the tackifier dispersed therein; then, reacting the first blend with a silane to provide a non-tacky thermoplastic vulcanizate product.
