  • High exchange capacity perfluorinated ion exchange resin, preparation method and use thereof
    Patent number: 9090723
    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%.
