ABSTRACT:
Water-swellable, cross-linked, bead copolymers of (A) an ethylenically unsaturated monomer having a carboxylic acid anhydride, glycidyl or succinimide group, (B) a comonomer having at least two radical-polymerizable carbon double bonds, and (C) a radical-polymerizable water-soluble comonomer are disclosed to be excellent carriers capable of bonding with biologically active substances such as enzymes, enzyme substrates, inhibitors, hormones, antibiotics, antigens, and peptides.
