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
QRk(+), 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: R2SOx
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.
