Abstract
The invention relates to a novel synthesis method for forming superacid functional molecules that include monomers, as well as new polymers and copolymers formed from the monomers, and uses for these superacid molecules, polymers, and copolymers. The superacid molecules have an alpha, alpha-difluorosulfonic acid functionality that can be obtained by a reaction between various Grignard reagents and an alkyl(2-fluorosulfonyl)-1,1-difluoroacetate, such as methyl (2-fluorosulfonyl-1,1-difluoroacetate. The molecules, polymers and copolymers would be expected to have enhanced ion conductivity, and would be useful in a variety of applications, including as ion-conductive materials, surfactants, and ion exchange resins.
