WATER-ABSORBING RESIN SUITABLE FOR USE IN SANITARY PRODUCTS

摘要

The invention provides a water-absorbing resin produced by reversed-phase suspension polymerization which is reduced in the residue therein of petroleum hydrocarbon used in the reversed-phase suspension polymerization as the dispersion medium and thereby lowered in the smell of petroleum hydrocarbon generated when the resin absorbs water and which is suitable for use in sanitary products; absorbers; and absorbent articles. More particularly, a water-absorbing resin obtained by reversed-phase suspension polymerization of an aqueous solution of a water-soluble ethylenically unsaturated monomer in a petroleum hydrocarbon dispersion medium in the presence of a surfactant, wherein the residue of the petroleum hydrocarbon dispersion medium in the resin is 2,000ppm or below; and absorbers and absorbent articles, made by using the resin.
