Document Type and Number:
Japanese Patent JP2013513707
Kind Code:
A
Abstract:
The present invention provides a high exchange capacity perfluorinated resin comprising two kinds of sulfonyl fluoride-containing short pendant groups of different structures, which is prepared by copolymerizing tetrafluoroethylene, vinyl ether monomers comprising two kinds of sulfonyl fluoride-containing short pendant groups of different structures, and vinyl ether monomer comprising bromine-containing pendant group, wherein based on all monomer units in the copolymer, the mol % of tetrafluoroethylene monomer is 50-85%, the mol % of vinyl ether monomers comprising two kinds of sulfonyl fluoride-containing short pendant groups of different structures is 5-49% and the mol % of vinyl ether monomer comprising bromine-containing pendant group is 1-10%. Perfluorinated ion exchanges membrane prepared from such perfluorinated resin have resistance to various chemical media, high ion exchange capacity, high conductivity, high mechanical strength, high size stability, low membrane electrical resistance and long service life, and may be applied in fuel cells or high-temperature fuel cells.
