A simple molding process carried out within the confines of a closed mold has been used to prepare porous polymer monoliths. The polymerization is carried out using a mixture of monomers, propogenic solvent, and free-radical initiator under conditions that afford macroporous materials with through-pores or channels large enough to provide the high flow characteristics required for their applications. The versatility of the technique was demonstrated by its use with both hydrophobic and hydrophilic monomers such as styrene, (chloromethyl) styrene, glycidyl methacrylate, alkyl methcarylates, 2-(acrylamido)-2-methyl-1-propanesulfonic acid, acrylic acid, and acrylamide.
