  • Method for preparing fluorosulfonyl imide monomer
    Patent number: 6790990
    Abstract: Disclosed is a method for the preparation of a fluorosulfonyl imide monomer of the structure represented by formula (IV), wherein X is F or perfluoroalkyl having 1-4 carbons optionally substituted by ether oxygen, M is an alkali or alkaline earth metal when y is respectively 1 or 2, R is aryl, fluoro-aryl, or XCF2-where X is H, halogen, fluorinated or non-fluorinated linear or cyclic alkyl having 1-10 carbons, optionally substituted by one or more ether oxygens. Such monomers are useful for forming ionomers useful in electrochemical applications such as batteries, fuel cells, electrolysis cells, ion exchange membranes, sensors, electrochemical capacitors, strong acid catalysts, and modified electrodes.
