  • Sulfonated polymers useful for forming fuel cell membranes
    Patent number: 9184459
    Abstract: The invention relates to a polymer comprising at least one polymeric chain of a first type, the said chain comprising at least two blocks, the same or different, the said blocks comprising repeat units derived from the polymerisation of styrene monomers, the said units comprising at least one phenyl pendant group carrying at least one —SO3R group, R possibly being a hydrogen atom, an alkyl group or cationic counter-ion, the said two blocks being separated by a spacer group, the spacer group is a perfluorocarbon group.

  • Copolycondensation polymerization of fluoropolymers
    Patent number: 8247614
    Abstract: Fluorinated copolymers are prepared via copolycondensation polymerization in a process comprising reacting A) a telechelic fluoroazido compound of formula N3(Y)p—(CH2)n—R—(CH2)m—(Y)pN3, wherein Y is SO, SO2, C6H4, or CO, p=0 or 1, n and m are independently 1 to 4, and R is selected from the group consisting of i) a C3-C10 fluoroalkylene group, ii) a C3-C10 fluoroalkoxylene group, iii) a substituted aryl group, iv) an oligomer comprising copolymerized units of vinylidene fluoride and perfluoro(methyl vinyl ether), v) an oligomer comprising copolymerized units of vinylidene fluoride and hexafluoropropylene, vi) an oligomer comprising copolymerized units of tetrafluoroethylene and perfluoro(methyl vinyl ether), and vii) an oligomer comprising copolymerized units of tetrafluoroethylene and a hydrocarbon olefin with B) a telechelic diyne or dinitrile compound in the presence of copper halide catalyst.
