A composition of (a) a fluoropolymer having interpolymerized units derived from a nitrogen-containing cure site monomer; and (b) a nonfluorinated catalyst composition that includes a compound having the general formula: {RA}(−){QR′k}(+) or in certain cases the precursors thereof, wherein R is hydrogen, an 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 R2—OH, wherein R2 is an alkyl group which can be partially fluorinated. Also provided are a method of making a fluoropolymer, a method of increasing induction time, and fluoropolymer articles containing curable or cured fluoropolymer compositions.
