In this work light sulfonation was applied to a styrene copolymer crosslinked with divinylbenzene (PS‐ co ‐DVB). Subsequently the product was incorporated at different concentrations into poly(vinylidene fluoride) (PVDF) and ethylene‐propylene‐diene (EPDM). Also, antimonic acid (HSb) was added. The resulting composites were characterized both microstructurally and electrically. In addition, PVDF/PS‐ co ‐DVBSH/HSb and EPDM/PS‐ co ‐DVBSH/HSb membranes were sulfonated, utilizing chlorosulfonic acid as a reagent, and characterized electrically. The membranes obtained by this procedure show good properties from an electric point of view.
