Abstract
Experimental researches on the preparation of porous polymeric monoliths in supercritical carbon dioxide have been performed and the effects of monomer and polymerization parameters on the physical properties of the monolith prepared were examined. Polymerizations were carried out in the high pressure stainless steel reactor with sapphire window to show the phase change during the polymerization reaction, and continuous and dry porous monolithic polymer could be obtained. The specific surface area of monolithic polymer increased with monomer contents in reaction mixture and reaction pressure. The Rockwell hardness could be enhanced by the addition of co-monomer MMA in reaction mixtures.
