ABSTRACT:
A predetermined mass comprising an acrylate salt and acrylamide is exposed to a controlled intensity and dose of ionizing radiation effecting simultaneous cross-linking and polymerization thereof to form a polyelectrolyte hydrogel. The resulting hydrogel is an insoluble hydrophilic copolymer which can contain or when dried absorb large quantities of aqueous fluids.
