A branched aromatic ionomer is prepared with a first monomer having an unsaturated moiety and a second monomer having an unsaturated moiety and an ionic moiety, wherein the ionic moiety comprises a polyvalent metal with a coordination number greater than its oxidation number. An example of the first monomer is styrene, and the product ionomer can be a variety of general purpose polystyrene. Examples of the second monomer are zirconium methacrylate and titanium methacrylate, which may be co-polymerized with at least 0.5 molar equivalents of methacrylic acid as an in-situ formed ionomeric crosslinker.
