Abstract: An insoluble biocatalyst is prepared by forming a mixture consisting essentially of the biocatalyst, one or more water-soluble compounds having two or more acrylamide or meth-acrylamido groups and one or more water soluble amines possessing two or more hydrogen atoms bonded to an amine nitrogen, and forming a gel from the mixture. The water-soluble amine is selected from ammonia, lower diamines, lower polyamines, primary monoamines, polyethyleneimine and polyvinylamine. Beads containing the biocatalyst may be formed by suspending the mixture in a water-immiscible solvent to form droplets prior to gelling. The biocatalyst may be an enzyme, cells or cell fragments.

Abstract: A process for the preparation of insoluble, only slightly swellable, granular polymers of basic vinyl-heterocyclic compounds and of their copolymers with up to 30% by weight of copolymerizable monomers and 0.1-10% by weight of crosslinking agent by exclusion of (atmospheric) oxygen from the mixture of monomer and crosslinking agent, without addition of any initiator or catalyst, and the use of the polymers obtained as ion exchangers, adsorbents and carriers for proteins.
