Abstract
Metal ion crosslinked superabsorbent polymers and a process for making them are described wherein high concentrations of polyhydroxylated materials are incorporated in order to reduce the sensitivity of the superabsorbent composition to solutions containing dissolved salts. Also provided is a process for forming crosslinked superabsorbents containing high solids polymer content.
