Abstract
High internal phase emulsions having an internal aqueous phase of greater than 70 percent by volume and an external oil phase comprising a vinyl polymerizable monomer contain a surfactant capable of chemically binding to the polymerizable monomer. Polymeric foams having a high internal phase emulsion stabilizing surfactant chemically bound to the polymeric material and a liquid capacity of from about 70 to 99 percent of its saturated volume can be prepared from such emulsions.
