Abstract
In its broadest sense of the present invention comprises an aqueous emulsion containing water, a normally thermoplastic sulfonated polymer and a plasticizer that is substantially miscible in the polymer is, non-volatile and substantially insoluble in the water phase of the emulsion. The aqueous emulsion of the present invention is formed by polymerizing a sulfonate containing monomer with at least one non-sulfonate containing monomer in the aqueous phase in the presence of a free radical initiator and in the presence of a plasticizer that is substantially miscible in the polymer, is non-volatile and substantially water insoluble.
