Abstract: An ion exchange polymer is provided. The ion exchange polymer is a reaction product of a reaction between a crosslinker monomer and a cationic monomer. The crosslinker monomer is a reaction product of a reaction between a first crosslinking monomer and a second crosslinking monomer. Further, the cationic monomer comprises a quaternary ammonium group. A method for making an ion exchange polymer is also provided. The method comprises a step of preparing a curable solution and a step of curing the curable solution. The step of preparing the curable solution comprises mixing a pair of crosslinking monomers, a cationic monomer that comprises a quaternary ammonium group and an acid. A membrane is also provided. The membrane comprises the ion exchange polymer made by the method provided.
