ABSTRACT:
Water absorbent compositions comprise a water swellable polymer which contains polymerized water-soluble monomers, water-insoluble monomers having a pendant hydrophobic moiety, and optionally, a crosslinking monomer. The polymer can be blended with a colloidal support such as colloidal silica. The compositions exhibit good water absorbency rates and high gel strengths.
