Abstract
Relatively thin, collapsed, i.e. unexpanded, polymeric foam materials that, upon contact with aqueous body fluids, expand and absorb such fluids, are disclosed. A process for consistently obtaining such relatively thin, collapsed polymeric foam materials by polymerizing a specific type of water-in-oil emulsion, commonly known as High Internal Phase Emulsions or 'HIPE', is also disclosed.
