  • Bisaminophenyl-based curatives and amidine-based curatives and cure accelerators for perfluoroelastomeric compositions
    Patent number: 7247749
    Abstract: Novel monoamidine, monoamidoxime and bisamidine curatives, co-curatives and cure accelerators are provided for use with perfluoroelastomeric compositions as well as novel synthesis methods for making monoamidine- and monoamidoxime-based curatives, co-curatives and cure accelerators. Also provided are diphenyl-based curatives, co-curatives and cure accelerators having sufficiently high molecular weight such that the melting temperature of the curatives, co-curatives and cure accelerators is no greater than about 240° C., and more preferably no greater than about 230° C.
    Type: Grant
    Filed: January 29, 2004
    Date of Patent: July 24, 2007
    Assignees: Greene, Tweed of Delaware, Inc., Federal State Unitary Enterprise S.V. Lebedev Institute of Synthetic Rubber
    Inventors: Carl A. Aufdermarsh, Harshad P. Amin, Anestis Logothetis, Victor Gubanov, Margarita Volkova, Lioudmila Karmanova, Alexandr Kollar, Polina Troichanskaia, Gennady Emelianov, Vsevolod Berenblit
