ABSTRACT:
The present invention relates to compressable polymeric foam materials useful as insulation. These polymeric foams are prepared by polymerization of certain water-in-oil emulsions having a relatively high ratio of water phase to oil phase, commonly known as "HIPEs." The polymeric foam materials comprise a generally hydrophobic, flexible or semi-flexible, nonionic polymeric foam structure of interconnected open-cells. The foam structures have:
