    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.

    IPC: C08F214/26

    Abstract: Described herein is a fluorothermoplast with long chain branching and a method of making such a polymer using a modifier of the formula: F2C═CF(CF2)a(O)RfH wherein a is 0 or 1 and Rf is a linear or branched fluorinated alkylene group comprising 1 to 5 carbon atoms and optionally comprising at least one ether linkage and optionally comprising 1 or 2 hydrogen atoms. This fluorothermoplast may be processed through polymer melt processes, such as blow molding, injection molding, film extrusion, and wire extrusion. Preferably, said polymer contains structural units derived from tetrafluoroethylene and a perfluorinated olefin or ether, and comprises chain branching.

    Abstract: Described are methods of making a curable fluoropolymer having repeating units derived from vinylidenfluoride (VDF) and at least one perfluorinated monomer selected from hexafluoropropene (HFP), tetrafluoroethene (TFE), a perfluorovinyl ether (PAVE), a perfluoroallylether (PAAVE) or a combination thereof. The method includes polymerising the monomers in an aqueous medium in a radical reaction containing one or more reaction initiators, one or more chain transfer agent containing one or more halogens selected from iodine, bromine or a combination thereof and one or more non-fluorinated aliphatic polyhydroxy emulsifiers. The polymerization is carried out without adding a fluorinated emulsifier. Also provided are curable fluoropolymers obtainable by such methods and cured fluoropolymers obtainable by curing the curable fluoropolymers, and their applications.
