Abstract
Enzymes are immobilized by entrappment or by covalent bonding with alkali saponified gelatinized-starch-polyacrylonitrile graft polymers. The polymers absorb amounts of water equaling up to more than 1000 times their own weight. In addition to immobilizing enzymes, the polymers find many applications including their incorporation into products such as disposable diapers, surgical pads and sheets, and paper towels.
