Abstract
A novel anion exchange polymer is provided. A method of making the anion exchange polymer includes reacting a tertiary amine, an acid inhibitor and a polyepoxide to form a quaternary ammonium monomer and polymerizing the quaternary ammonium monomer in the presence of a catalyst. The exchange polymer is prepared without using alkyl halides and can be used to make improved ion exchange materials that are chemically resistant and non-fouling.
