Abstract
Carriers for immobilizing enzymes may be prepared by suspension copolymerizing an oxirane-group-bearing, monovinyl monomer and a major amount of a trivinyl crosslinking monomer having a hydrophilic character, in the presence of a phase separator which does not react with the oxirane group. The resulting carriers, in bead form, have high porosity, high surface area, and pores of diameter sufficient for ready penetration by enzymes and substrates.
