    摘要： A composition of a fluoropolymer comprising interpolymerized units of nitrogen-containing cure site monomer and a catalyst comprising a compound having the formula: wherein HA is an acid, each R1, R2, and R3 is independently a C1-C20 alkyl group, which may be cyclic or heterocyclic, or Rf(CH2)n— wherein Rf is a C1-C8 linear or branched and at least partially fluorinated, and x is 1 to 4, and one R group may be a bond to another R group such that the nitrogen is bonded to or part of an alkenyl, cycloalkenyl, or aromatic group. This may further comprise a catalyst composition comprising a compound of the formula R1C(OR2)═NH, and salts thereof, where each R1 and R2 is, independently, a substituted or unsubstituted alkyl, aryl, aralkyl, alkenyl, cycloalkyl, or cycloalkenyl. Also provided are a method of making a fluoropolymer composition and articles prepared from the compositions.

    摘要： Fluorinated emulsifiers can be recovered from an aqueous phase containing small amounts of fluoropolymer particles by treating the aqueous phase with a small amount of a nonionic surface-active agent, bringing the aqueous phase adjusted in this way into contact with an anionic exchanger resin, and liberating the adsorbed emulsifier from the exchanger resin. The finely divided fluoropolymer can be precipitated quantitatively in the untreated aqueous phase or the eluate using flocculating agents.
