  • Aqueous process for making fluoropolymers
    Patent number: 8765890
    Abstract: A novel aqueous polymerization process for making fluoropolymer dispersions is disclosed in which non-ionic non-fluorinated emulsifier is used to produce fluoropolymer emulsions. The emulsifiers contain blocks of polyethylene glycol, polypropylene glycol and/or polytetramethylene glycol. The process and fluoropolymer produced contain no fluorinated surfactant. The fluoropolymers have excellent resistance to discoloration.
    Type: Grant
    Filed: November 16, 2011
    Date of Patent: July 1, 2014
    Assignee: Arkema Inc.
    Inventors: Ramin Amin-Sanayei, Mehdi Durali, Patrick Kappler, Greylan Burch
