Abstract
High internal phase emulsions (HIPEs), porous polymeric materials made therefrom, and methods for making and using the same. Specific embodiments of the invention include water-in-oil high internal phase emulsions having at least 70 volume percent of an internal aqueous phase and less than 30 volume percent of an external oil phase wherein the oil phase comprises a vinyl polymerizable monomer and a surfactant effective to stabilize the emulsion. The subject surfactants are oil soluble and preferably include an oxyalkylene component.
