Abstract
A branched aromatic ionomer is prepared by co-polymerizing a first monomer having an aromatic moiety and an unsaturated alkyl moiety and a second monomer having an ionic moiety and at least one unsaturated moiety. The ionic moiety may have a cationic group having a valence of +1 or greater. Styrene is among the useful first monomers and sodium methacrylate and zinc dimethacrylate are among the useful second monomers. The branched aromatic ionomers may be used to prepare articles including foamed polystyrene and microwave save dishes and utensils.
