Abstract
Official abstract text for this publication.
The present invention provides a perfluorinated ion exchange resin, whose structural formula is shown in formula M. The present invention also provides preparation method of the perfluorinated ion exchange resin, comprising subjecting tetrafluoroethylene monomers and two kinds of sulfonyl fluoride-containing vinyl ether monomers in the presence of initiator to ternary copolymerization. The perfluorinated ion exchange resin provided in accordance with the present invention can fulfill the requirements of mechanical strength and ion exchange capacity at the same time and has good thermal stability.
First claim
Opening claim text (preview).
The invention claimed is: 1. A perfluorinated ion exchange resin, characterized in that the structure of said perfluorinated ion exchange is shown in formula M: wherein a and b are an integer between 3 and 15 respectively, while a′ and b′ are an integer between 1 and 3 respectively; x/(x+y)=0.2-0.8, y/(x+y)=0.2-0.8; (ax+by)/(ax+a′x+by+b′y)×100%=50-93.75%, (a′x+b′y)/(ax+a′x+by+b…
