A composition comprising a fluoropolymer comprising interpolymer units of a nitrogen-containing cure site monomer and a catalyst comprising a compound of the specific formula, a process for its production and an article prepared from the composition. The formula: R 1 R 2 R 3 N · HA [HA: acid. Each R 1, R 2, R 3 : cyclic or heterocyclic C 1 -C 20 alkyl group or R f, - (CH 2) x - (R f: C 1 ~C 8 straight or branched chain And partially fluorinated, x: 1 to 4). One R group: Nitrogen may be bonded to an alkenyl group, cycloalkenyl group or aromatic group, or may be single bonded to another R group so that it is part of an alkenyl group, cycloalkenyl group or aromatic group ] Compound. The composition comprises a compound having the formula R 1 C (OR 2 ) ═NH (R 1 , R 2 : independently substituted or unsubstituted alkyl, aryl, aralkyl, alkenyl, cycloalkyl or cycloalkenyl) and salts thereof The catalyst composition may also be included.
