Abstract
The present disclosure is directed to using a blend of sorbitan esters as a surfactant to produce a stable water-in-oil high internal phase emulsion in the preparation of a low density porous crosslinked polymeric material. This process produces low density, high capacity, porous, crosslinked, polymeric materials with improved absorption capacity and foam properties.
