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 R 1 , R 2 , and R 3 is independently a C 1 -C 20 alkyl group, which may be cyclic or heterocyclic, or R f (CH 2 ) x - wherein R f is a C 1 -C 8 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 R 1 C(OR 2 )-NH, and salts thereof, where each R 1 and R 2 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.

IPC分类号： C08F214/18
摘要： A method is provided for aqueous emulsion co-polymerization of two or more fluoromonomers comprising the steps of: 1) forming an aqueous pre-emulsion by mixing a fluoromonomer according to formula I: F 2 C-CF-R 1 -SO 2 X (I) wherein R 1 is a branched or unbranched perfluoroalkyl, perfluoroalkoxy or perfluoroether group comprising 1-15 carbon atoms and 0-4 oxygen atoms and wherein X is F, Cl or Br, together with 0.001-0.9 molar equivalents of a base, in the absence of added emulsifier; and 2) reacting the pre-emulsion with one or more perfluorinated comonomers in the absence of added emulsifier so as to form a fluoropolymer latex comprising a fluoropolymer wherein more than 1 mol % of monomer units are derived from the fluoromonomer according to formula I. In another aspect, the present invention provides a fluoropolymer derived from the fluoropolymer latex made according to the method of the present invention which is free of added emulsifier. In another aspect, the present invention provides a polymer electrolyte membrane comprising the fluoropolymer made according to the method of the present invention which is free of added emulsifier.
