Methacrylate-based monoliths are formed during radical copolymerization as a consequence of the precipitation of polymeric chains from the reaction mixture, which consists of monomers, initiator, and the porogenic solvents. The effect of various methacrylate monomers on the porous structure of the monolith was investigated. Although the chemical structure of the monomers significantly affects the size of the pores and the porosity, the mechanism of pore formation in the case of the precipitation during polymerization is preserved. The porous structure was further correlated with the specific surface area, pressure drop, and dynamic binding capacity of the monoliths studied.
