ABSTRACT OF THE DISCLOSURE A method for the production of a fluid stable aggregate, 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, and (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 which is provided with an inner surface formed substantially of a substrate (I) possessing a contact angle of not less than about 60° with respect to water and a heat distortion point of not lower than about 70°C under the stirring condition of not less than 600 m/min of a peripheral speed of a leading-end of a stirring blade and thereafter completing reaction of said absorbent resin powder (A) with said cross-linking agent (B) under the condition that total kinetic energy F added to a mixture during the reaction is satisfied by the following equation: 0 ? F ? 36,000 joule/kg wherein the kinetic energy Fa per minute added during the reaction is not more than 600 joule/kg.
