ABSTRACT:
This invention relates to heterogeneous elastomeric blends having improved rheological properties of a major portion of a neutralized sulfonated elastomeric polymer with a minor portion of a polystyrene thermoplastic resin or a neutralized sulfonated polystyrene resin and mixtures thereof. Both the sulfonated elastomeric polymer and the sulfonated thermoplastic resin have about 0.2 to about 10.0 mole percent of SO.sub.3 H groups, at least 90% of which are neutralized with an organic amine.
