Patent ID: 7514506

Claim:
A fluoroelastomeric composition comprising: (a) at least one curable fluoropolymer comprising at least one functional group for crosslinking the fluoropolymer, wherein the at least one curable fluoropolymer is a perfluoropolymer which comprises a polymer of tetrafluoroethylene, a perfluoroalkylvinyl ether and at least one curesite monomer, wherein the at least one functional group for crosslinking the fluoropolymer is located on the at least one curesite monomer; (b) a curative capable of crosslinking the at least one fluoropolymer selected from the group consisting of functionalized biphenyl-based compounds, compounds according to formula (I): wherein Y is selected from the group consisting of substituted alkyl, alkoxy, aryl, aralkyl or aralkoxy groups of from 1 to about 22 carbon atoms; substituted or unsubstituted halogenated alkyl, alkoxy, aryl, aralkyl or aralkoxy groups of from about 1 to about 22 carbon atoms, and perfluoroalkyl, perfluoroalkoxy, perfluoroaryl, perfluoroaralkyl or perfluoroaralkoxy groups of from 1 to about 22 carbon atoms; and R 1 is hydrogen; substituted or unsubstituted lower alkyl or alkoxy groups of from 1 to about 6 carbon atoms; and an amino group; and R 2 is R 1 or hydroxyl, compounds according to formula (II): wherein D is selected from the group consisting of unsubstituted or substituted halogenated alkyl, alkoxy, aryl, aralkyl or aralkoxy groups having from about 1 to about 22 carbon atoms; and perfluoroalkyl, perfluoroalkoxy, perfluoroaryl, perfluoroaralkyl or perfluoroalkoxy groups of from 1 to about 22 carbon atoms; and R 1 and R 2 are each independently selected to be hydrogen; substituted or unsubstituted lower alkyl or alkoxy groups of from 1 to about 6 carbon atoms and an amino group, and combinations thereof; and (c) at least one cure accelerator comprising a peroxide.
