Compositions comprising a fluoropolymer having interpolymerized units derive d from a nitrogen-containing cure site monomer and a catalyst composition are provided. The catalyst composition includes a compound having the general formula:{RA}(-){QR'k}(+) 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 o f Q; and optionally (c) an alcohol of the formula R2-OH, wherein R2 is an alky l group which can be 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.
