Abstract
A process for forming a thermoplastic vulcanizate compromising the steps of dynamically vulcanizing a rubber within a blend that comprises the rubber and a thermoplastic polymer, where said step of vulcanizing is carried out by using a phenolic resin in the presence of a catalyst system formed by combining a metal halide and a metal carboxylate. Also, a thermoplastic vulcanizate having low moisture pick-up with a technologically useful cure.
