ResumoAbstract Sulfomethylated and sulfopropylated resins were prepared by polymer analogous reactions, starting from macroporous poly(styrene‐ co ‐divinylbenzene) matrices. Different reaction paths were used in the synthesis. It could be shown that sulfoalkylation can be achieved directly by reaction of the polystyrene resins with sultones. Alternatively, haloalkylated matrices were prepared and by halogen/sulfo‐substitution the corresponding ion exchange resins.
