Abstract
PURPOSE: To improve dispersion in water and speed of water absorption of the titled polymer without damaging water absorption, by a water absorbing resin comprising an alkali salt of acrylic acid as an ingredient into a specific mixed solvent, followed by crosslinking it with a bifunctional crosslinking agent.
CONSTITUTION: (A) A water absorbing resin comprising an alkali salt of acrylic acid as an ingredient of a polymer is dispersed in a mixed solvent containing preferably 50W95wt% hydrophilic organic solvent (the most preferably methyl alcohol) and water, (B) a crosslinking agent (e.g., epichlorohydrin, etc.) having a bifunctional group capable of being reacted with carboxylate is added to the resin, and crosslinking is carried out at preferably 40W150°C. The amount of the component B used is preferably 0.005W5wt% based on ingredient A.
