    Abstract: A method of making a highly fluorinated polymers and resulting aqueous mixtures. The method comprising polymerizing one or more perfluorinated monomers in an aqueous emulsion polymerization in the presence of a polymerizable fluorinated emulsifier to form a perfluorinated polymer. The polymerizable fluorinated emulsifier has the formula X2C═CX(CF2)m(CH2)n[O—(CX2)p]q—[O—(CX2)r]s—[O—(CX2—CX2)]t—[(O)w—(CX2)u]v—[CH2]z—Y. The method also provides for isolating the highly fluorinated polymer and post-fluorinating the isolated highly fluorinated polymer.

    Abstract: Provided are methods for removing a perfluorinated alkanoic acid from solutions containing the perfluorinated alkanoic acid and a fluorinated alkoxy acid. These methods include contacting the first solution with an anion-exchange resin to produce a second solution and a resultant anion-exchange resin having perfluorinated alkanoic acid adsorbed thereto, wherein the perfluorinated alkanoic acid is present in the first solution at a first concentration and is present in the second solution at a second concentration which is lower than the first concentration, and separating the second solution from the resultant anion-exchange resin.

    Abstract: The copolymer includes divalent units represented by formula: (I), one or more independently selected fluorinated divalent units, and —SO2X end groups. In this formula, b is 2 to 8, c is 0 to 2, and e is 1 to 8. In each SO2X, X is independently F, —NZH, —NZSO2(CF2)1−6SO2X′, —NZ[SO2(CF2)aSO2NZ]1−10SO2X′, or —OZ, wherein Z is a hydrogen, an alkali-metal cation or a quaternary ammonium cation, X′ is independently —NZH or —OZ, and each a is independently 1 to 6. The copolymer has an —SO2X equivalent weight of up to 1000. The method includes copolymerizing components including fluorinated olefin and a compound represented by formula CF2═CF—CF2(O—CbF2b)c—O—(CeF2e)—SO2X′, wherein b, c, and e are as defined above. A method of making a membrane using the copolymer or ionomer is also provided. A polymer electrolyte membrane that includes the copolymer or the ionomer and a membrane electrode assembly that includes such a polymer electrolyte membrane are also provided.
