FLUORPOLYMERZUSAMMENSETZUNGEN

Compositions comprising a fluoropolymer derived from a nitrogen-containing cure site monomer, a catalyst composition which comprises at least one anionic functional group and at least one cationic functional group having the formula QR'k(+), wherein Q is selected from phosphorous, sulfur, nitrogen, arsenic, or antimony, wherein each R' is independently selected from hydrogen and a nonfluorinated, partially fluorinated, or perfluorinated, C1-C20 alkyl, aryl, aralkyl, or alkenyl group, and wherein k is the valence of Q plus one; wherein the catalyst composition is a compound or the precursors thereof added separately or as a mixture; and a composition of the formula: R''2SOx wherein each R'' is C1-C30 alkyl, aralkyl, the two R'' groups together form a heterocyclic C3-C30 cycloalkyl, aryl, or aralkyl, each R'' can be fluorinated, and x is 1 or 2. Also provided are methods of making a fluoropolymer and fluoropolymer articles containing fluoropolymer compositions.
