  • Curable base-resistant fluoroelastomers
    Patent number: 6924344
    Abstract: Compositions of specialty fluoroelastomers containing copolymerized units of tetrafluoroethylene, propylene, optionally vinylidene fluoride, and a cure site monomer selected from the group consisting of i) trifluoroethylene, ii) 3,3,3-trifluoropropene-1, iii) 1,2,3,3,3-pentafluoropropylene, iv) 1,1,3,3,3-pentafluoropropylene, and v) 2,3,3,3-tetrafluoropropene are readily curable with polyhydroxy curing systems. The resulting cured articles have a combination of excellent resistance to alkaline fluids, superior tensile properties and compression set resistance.
    Type: Grant
    Filed: November 24, 2003
    Date of Patent: August 2, 2005
    Assignee: DuPont Dow Elastomers LLC
    Inventors: John Gordon Bauerle, Walter Werner Schmiegel
