The synthesis method of perfluorovinyl ether monomer is as follows:
Using perfluorovinyl ether containing sulfonyl fluoride group and tetrafluoroethylene and hexafluoropropylene monomer* By polymerization, perfluorosulfonic acid resin can be obtained. The polymer obtained in this way is a sulfonyl fluoride type (-SO2F), which needs to be hydrolyzed into an ionic type (-SO3M) when used in an electrolytic cell, where M is a metal ion such as H or K or Na. The strongest super liquid acid is trifluoromethanesulfonic acid.
