Abstract
A process for the preparation of an absorbent polymeric composition is disclosed. The process involves the polymerization of an aqueous solution of carboxylic acid monomers in a neutralized or partially neutralized form in the presence of a dispersing agent which aids in the even dispersion of the crosslinking agent. The polymers prepared exhibit high absorptive capacities and low water-soluble polymer content.
