A perfluorinated ionic resin |
| abstract |
The invention discloses a perfluorinated ionic resin comprising at least a structural unit of a tetrafluoroethylene monomer, a structural unit of a sulfonyl fluoride monomer and a structural unit of a perfluoropolyether monomer; the perfluoropolyether monomer It can be represented by the formula PFPE-(CF 2 -OCF=CF 2 ) α , where α is an integer of 1 or 2, PFPE is a perfluoropolyether obtained by free radical oxidation of tetrafluoroethylene, and the number of perfluoropolyether monomers The average molecular weight is above 500. The perfluorinated ionic resin of the present invention is obtained by modifying a perfluoropolyether monomer derived from tetrafluoroethylene, and the ion exchange membrane prepared from the resin can maintain excellent mechanical strength even at a higher capacity, and the preparation The ion exchange membrane has good thermal stability and corrosion resistance. |
