    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: F2C═CF—R1—SO2X  (I) wherein R1 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.

    摘要： A composition including at least one first divalent unit represented by formula: Each Rf is independently selected from the group consisting of Rfa—(O)t—CHF—(CF2)n—; [Rfa—(O)t—C(L)H—CF2—O]m—W—; Rfb-O—(CF2)p-; F(CkF2k)—(O—CkF2k)P—O—CF2—; and CF3—O—(CF2)3—(OCF(CF3)—CF2)Z—O-L1-. Each Q is independently selected from the group consisting of a bond, —C(O)—N(R1)—, and —C(O)—O—. Each X is independently selected from the group consisting of alkylene and arylalkylene, wherein alkylene and arylalkylene are each optionally interrupted by at least one ether linkage and optionally terminated by —N(R1)—C(O)— or —O—C(O)—. R and R1 are each independently selected from the group consisting of hydrogen and alkyl having from 1 to 4 carbon atoms. Rfa represents a partially or fully fluorinated alkyl group having from 1 to 10 carbon atoms and optionally interrupted with at least one oxygen atom. Rfb is selected from the group consisting of CF3CFH— and F(CjF2j)-. Methods of reducing surface tension of a liquid, making foams, and treating a surface using the compositions are also disclosed.
