Patent ID: 6890995

Claim:
A composition comprising: (a) a fluoropolymer comprising interpolymerized units derived from a nitrogen-containing cure site monomer; (b) a catalyst composition that includes a compound having the general formula: {R(A) n } (−n) {QR′ k (+) } n or the precursors thereof added separately or as a mixture; wherein R is a C 1 -C 20 alkyl or alkenyl, C 3 -C 20 cycloalkyl or cycloalkenyl, or C 6 -C 20 aryl or aralkyl, which may be nonfluorinated, partially fluorinated, or perfluorinated, {R(A) n } (−n) is an acid anion or an acid derivative anion, n is the number of A groups in the anion, Q is phosphorous, sulfur, nitrogen, arsenic, or antimony, each R′ is, independently, hydrogen or a substituted or unsubstituted C 1 -C 20 alkyl, aryl, aralkyl, or alkenyl group, provided that when Q is nitrogen and the only fluoropolymer in the composition consists essentially of a terpolymer of tetrafluoroethylene, a perfluorovinylether, and a perfluorovinylether cure site monomer comprising a nitrile group not every R′ is H, and k is one greater than the valence of Q; and optionally (c) an alcohol of the general formula R 2 —OH, wherein R 2 is an alkyl group having from 1 to 20 carbon atoms, and wherein R 2 is optionally fluorinated.
