Miscibility enhancement of ionomer/ionomer and ionomer/polymeric acid systems is studied on the polymer pairs of poly(styrene‐co‐tetramethyl ammonium styrenesulfonate)/poly(ethyl acrylate‐co‐ N ‐methyl‐4‐vinylpyridinium iodide) and poly(styrene‐co‐styrenesulfonic acid)/poly(ethyl acrylate‐co‐ N ‐methyl‐4‐vinylpyridinium iodide). NMR and dynamic mechanical results show that in these blends direct macroion–macroion interaction can be achieved with the elimination of microcounterions from the polymer chains. Ion‐ion attraction leads to a miscibility enhancement comparable to that of the previously reported proton transfer blends; a miscible blend is obtained with ca. 5 mol% of ions in the polymers.
