摘要： A method of treating the surface of an absorbent resin, which comprises mixing (A) 100 parts by weight of an absorbent resin powder possessing a carboxyl group (B) 0.01 to 30 parts by weight of a cross-linking agent, (C) 0 to 50 parts by weight of water, and (D) 0 to 60 parts by weight of a hydrophilic organic solvent in a high-speed stirring type mixer provided with an inner surface formed substantially of a substrate (I) possessing a contact angle of not less than about 60.degree. with respect to water and a heat distortion point of not lower than about 70.degree. C. and completing reaction of said absorbent resin powder (A) with said cross-linking agent (B).
