  • Bisaminophenyl-based curatives and amidine-based curatives and cure accelerators for perfluoroelastomeric compositions
    Patent number: 7521510
    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: May 17, 2006
    Date of Patent: April 21, 2009
    Assignee: Greene, Tweed of Delaware, Inc
    Inventors: Carl A. Aufdermarsh, Harshad P. Amin, Anestis Logothetis
