ABSTRACT:
Superabsorbents made by the process of electron beam initiated polymerization of partially neutralized acrylic acid having improved absorbencies when a trivalent cationic salt, for example, Aluminum Acetate or a tetravalent cationic salt, for example, Platinum Tetrachloride, are added to the partially neutralized acrylic acid solution before polymerization is initiated.
