It is shown that ion pair-ion pair interactions can be utilized to achieve miscibility in blends of urethanes with styrene ionomers. The urethanes contain quaternary ammonium salts in the hard segments, while the styrenes contain sodium methacrylate groups (-9.6 mol %). By contrast, ion-dipole inter
