The method of claim 1 , wherein said polyelectrolyte (PED) is a vinyl polyelectrolyte. Suspensions in aqueous media of liquid droplets of water-insoluble compounds are useful for a variety of purposes. For example, when such droplets contain vinyl monomer and initiator, the monomer may undergo polymerization to form polymer particles in a process of suspension polymerization. Such polymer particles are useful for a variety of purposes, including, for example, as resins that are adsorptive or that have ion exchange functionality or both. Such resins are used for a wide variety purposes, including, for example, purification of foods and/or beverages.In the past, suspensions in aqueous media of liquid droplets of water-insoluble vinyl monomers have been stabilized by the addition of one or more stabilizing compound, and a common stabilizing compound is gelatin. Because gelatin is an animal product, many ...
