ABSTRACT:
An absorbent material is prepared by treating a substrate with an aqueous monomer dispersion of an acrylate salt and a cross-linking monomer and thereafter irradiating the treated substrate with high energy ionizing radiation to form a cage matrix of the polymer and monomer substrate. The absorbent material can be swelled with a solution containing a volatile additive to dispense said additive over a period of time.
