ABSTRACT:
A “high internal phase polymeric emulsion” (“HIPPE”) composition is described which comprises an emulsion of a discrete phase (component A) and a continuous phase (component B), wherein the volume fraction of the discrete phase is the majority fraction (on a volume basis) of the total volume of the emulsion. A compatibilizer, component C, is used to lower the interfacial tension between the phases containing components A and B. A process is described for creating such HIPPE composition in which the A component is a colloidal polymer particle.
