Abstract
Biological material such as enzymes is immobilized by adsorption or covalent bonding to a micro-porous water-insoluble acrylonitrile polymer containing from 20 .mu.M to 1000 .mu.M of amino groups per gram of the polymer. Covalent bonding may be carried out with a crosslinking or condensing agent. The amino groups may be introduced into the polymer by reduction of nitrile groups with lithium aluminum hydride in an inert non-solvent.
