A catalyst composition includes a compound having the general formula: {RA}<SUP>(-)</SUP>{QR'<SUB>k</SUB>}<SUP>(+)</SUP>or the precursors thereof, wherein R is a nonfluorinated, partially fluorinated, or perfluorinated alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl or aralkyl, A is an acid- or acid-derivative anion, Q is phosphorous, sulfur, nitrogen, arsenic, or antimony, and each R' is hydrogen or an alkyl, aryl, aralkyl, or alkenyl group, k is the valence of Q; and optionally (c) an alcohol of the formula: R<SUP>2</SUP>-OH, wherein R<SUP>2 </SUP>is an alkyl group which can be fluorinated. Also provided are curable and cured fluoropolymer compositions involving such a catalyst.
