Anion exchange polymers, methods for making and materials prepared therefrom

1. A method for making an anion exchange polymer comprising 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,

wherein the tertiary amine is an ethylenic tertiary amine, and

wherein the polyepoxide is a diglycidyl ether or a triglycidyl ether.
