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.
