constant temperature process of generating microcellular polymeric foams has been studied which employs supercritical carbon dioxide as the foaming agent. The process is based on phase separation in a solution of poly (methyl methacrylate) (PMMA) and supercritical CO;Typically, the process leads to a microcellular core structure encased by non-porous skin. Average cell sizes (0.5 to 15...
