Abstract
PURPOSE: To improve the water absorbing capacity of an anionic water absorbable resin in an ionic aqueous solution by using a sol forming substance, a neutralizing agent and a polymer as essential components of a water absorbing agent.
CONSTITUTION: Inorg. salts such as aluminum nitrate or aluminum chloride forming a sol by neutralization in an aqueous solution, a neutralizing agent (wherein said neutralizing agent may be a sol forming agent) and a water absorbable resin such as an insoluble polyacrylic acid type water absorbable resin or the like are used as three essential components to prepare the water absorbing agent. Then, if said water absorbing agent is used in an ionic aqueous solution, because salt resistance of an anionic water absorbable resin is improved, water absorbing capacity is enhanced.
