Abstract
Water-absorbing resin compositions obtained by adding a water-soluble thiol compound in the process of drying or pulverizing a hydrogel of a water-absorbing resin which is obtained by polymerizing a water-soluble monomer having a polymerizable unsaturated group optionally with a polysaccharide, in the presence of a crosslinking agent and water. Composition of the present invention are highly efficient in water absorption and safe for having extremely low amounts of residual monomer and water-soluble component.
