PERFLUORINATED ION EXCHANGE RESIN, PREPARATION METHOD AND USE THEREOF

摘要

Provided is a perfluorinated ion exchange resin, whose structural formula is shown as formula M. Also provided is preparation method of the perfluorinated ion exchange resin, including ternary copolymerization of tetrafluoroethylene monomer and two kinds of sulfonyl fluoride-containing vinyl ether monomers in the presence of initiator. The perfluorinated ion exchange resin provided can fulfill the requirements of mechanical strength and ion exchange capacity at the same time and has good thermal stability.
