  • Thermoplastic vulcanizate compositions
    Patent number: 11905401
    Abstract: In an embodiment, a thermoplastic vulcanizate (TPV) composition is provided. The TPV composition includes a thermoplastic polyolefin; and an ethylene based copolymer rubber, wherein the ethylene based copolymer rubber has: a Mw of from 500,000 g/mol to 3,000,000 g/mol, a Mw/Mn of 4.0 or lower, and a g?vis of 0.90 or greater. In another embodiment, a TPV composition includes a thermoplastic phase and an ethylene-propylene-diene terpolymer, wherein the thermoplastic vulcanizate composition has: a hardness of from 20 Shore A to 60 Shore D; and a stress relaxation slope of ?1 to ?5 (l/min) as measured by an Elastocon stress relaxation instrument.
    Type: Grant
    Filed: April 25, 2022
    Date of Patent: February 20, 2024
    Assignee: Celanese International Corporation
    Inventors: Antonios K. Doufas, Krishnan Anantha Narayana Iyer, Eric P Jourdain, Michael J. Goncy, Kelly Kirkendall, Katya N. Reyna
