Abstract: The use of salts, which are soluble in the aqueous bath in which they are employed, of polymers of the N-vinyl and/or N-allyl forms of nitrogen-containing heterocyclic compounds having 5 or 6 members in the heterocyclic ring system, from 1 to 100 mol-% of these compounds being quaternized with C1- to C12-alkyl groups and/or benzyl groups, as conditioning agents for the pretreatment of nonmetallic surfaces, before they are primed (given a nucleating treatment) for a subsequent chemical metallization. The metal coatings obtained using these conditioning agents are particularly uniform and adhere well.

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.

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.
