The synthesis of the macroporous copolymers which contain variable percentages of acrylonitrile or methyl methacrylate and ion exchangers, respectively, are investigated. The authors also studied the influence of the copolymerization parameters on the matrix structure as well as the sulfonation reaction with HSO 3 Cl. The sulfonation process of these macroporous matrices with HSO 3 Cl yields ion exchangers which contain sulfo and carboxyl groups. The total cation‐exchange capacities are roughly 4.0–5.0 meq/g.
