<p>PROBLEM TO BE SOLVED: To provide a water-absorbing resin foam that has a high water-absorbing property and in which the water-absorbing property does not decrease easily.SOLUTION: The water-absorbing resin foam production method is a method for producing water-absorbing resin foam by mixing and agitating gas into an aqueous liquid medium containing water-dispersive resin as a dispersoid, anionic surfactant as a frother, and water or mixture of water and water soluble solvent as a dispersion medium, to foam the aqueous liquid medium and produce foamed aqueous liquid medium, and by heating the foamed aqueous liquid medium to evaporate the dispersion medium and produce water-absorbing resin foam, and in which the aqueous liquid medium further contains a water-soluble polymer that is soluble in the dispersion medium.</p> |
