Abstract
A method of preparing a thermoplastic vulcanizate, the method comprising continuously dynamically vulcanizing a rubber within a blend with a thermoplastic resin, where the dynamic vulcanization is effected with a cure system that includes a free-radical cure agent, and a coagent-wetted carrier where the coagent-wetted carrier includes a multi-functional acrylate coagent, a multi-functional methacrylate coagent, or both a multi-functional acrylate and multi-functional methacrylate coagent.
