ABSTRACT:
A macroporous, hydrophilic enzyme carrier comprises a sulfonated polymer, charged with polyethyleneimine, of from 10 to 100% by weight of divinylbenzene, from 0 to 90% by weight of styrene and from 0 to 20% by weight of a copolymerizable monomer, the polyethyleneimine being neither crosslinked nor covalently bonded to the polymer.
