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.
Claims9
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.
The method acclaim 1 wherein the tertiary amine is selected from the group consisting of dimethylaminopropylmethacrylamide, dimethylaminopropylacrylamide, diethylaminopropylmethacrylamide, dimethylaminoethylmethacrylate and mixtures thereof.
