Abstract
The present invention is directed to a method for reducing monomer loss during curing of a high internal phase emulsion. The method has the steps of: forming a water-in-oil emulsion, curing the monomer component in the emulsion in a saturated steam environment, and forming a saturated polymeric foam material. The water-in-oil emulsion has an aqueous phase and an oil phase comprising a monomer component.
