Low density porous crosslinked polymeric materials

U.S. Patent Number: 5340842

Abstract: Stable high internal phase water-in-oil emulsions containing polymerizable vinyl monomers, crosslinking monomers and polymerization initiators are obtained by using saccharide fatty acid esters as surfactants. The amount of surfactants necessary to form stable high internal phase water-in-oil emulsions is decreased by using saccharide fatty acid esters as surfactants. Further, hydrophobic foams can be obtained by using saccharide fatty acid esters.
