  • Process for forming thermoplastic vulcanizates and thermoplastic vulcanizates made therefrom
    Patent number: 10730206
    Abstract: 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.
    Type: Grant
    Filed: December 10, 2015
    Date of Patent: August 4, 2020
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Declan Whelan, Stephen F. Roche, Porter C. Shannon
