ABSTRACT:
Superabsorbent polymeric compositions are prepared from monomer including acrylic acid and an effective amount of a second hydrophilic monomer, which can be a soluble salt of beta-acryloxypropionic acid. Preferably, the pH of the aqueous monomer solution is adjusted to substantially exclude free acid, and the aqueous monomer solution is coated onto a heated surface to both polymerize the monomer and dry the resulting hydrogel. Free acid thermal degradation products are avoided and the superabsorbent product has greater absorption capacity than acrylate homopolymer.
