Abstract
A method of making a polyurethane polymerized high internal phase emulsion (polyHIPE) is disclosed. The method involves preparing a polyurethane prepolymer and crosslinking the polyurethane prepolymer using a thiol-alkene Michael addition, producing a polyurethane polymerized high internal phase emulsion. In one embodiment, the polyurethane prepolymer is prepared by reacting diisocyanate and trimethylolpropaneallylether (TMPAE).
