  • Low density porous crosslinked polymeric materials
    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.
    Type: Grant
    Filed: January 19, 1994
    Date of Patent: August 23, 1994
    Assignee: Shell Oil Company
    Inventors: Robert P. Adamski, Maryanne Mores, Pui K. Wong, Diana D. Davis
