Date Jul. 9, 1998Disclosed are polymeric foam materials obtained using monomers based on silicon and/or germination. The copolymerization of silicon- or germanium-based monomers provide foams that have low glass transition temperatures and low densities. These foams also exhibit relatively high yield stress values, which make the foams suitable for absorption of fluids, particularly aqueous fluids such as urine and menses (when the foams are rendered hydrophilic). The foams have a variety of other uses, including insulation applications.
