Enzymes are immobilized on macroporous hydrophilic polymer beads by adsorption. The polymer beads are cross-linked, acrylate-based resins containing pendant hydroxy groups. The resins contain 10-70% methyl methacrylate, 10-70% methylacrylate, 5-14 40% ethylenically unsaturated monomer having at least one pendant hydroxyl group and 10-25% divinylbenzene. The resins provide immobilized enzyme preparations exhibiting excellent physical strength and stability as well as high enzyme activity.
