Provided are methods for producing a thermoplastic vulcanizate and thermoplastic vulcanizates provided therein. The method includes introducing vulcanizable rubber, thermoplastic resin, a masterbatch of a propylene-based elastomer and a cure accelerator for a phenolic resin curative to the reactor, and phenolic resin curative to a reactor and dynamically vulcanizing the rubber with the phenolic resin curative in the presence of the cure accelerator and the thermoplastic resin.

Process for forming thermoplastic vulcanizates and thermoplastic vulcanizates made therefrom

Provided are methods for producing a thermoplastic vulcanizate. One method includes charging vulcanizable rubber to a reactor; charging a masterbatch of thermoplastic resin and a catalyst for a phenolic resin curative to the reactor; charging a phenolic resin curative to the reactor; and dynamically vulcanizing the rubber with the phenolic resin curative in the presence of the catalyst. Also provided are thermoplastic vulcanizates made by the methods of the invention.
