Abstract
PURPOSE: To obtain a water absorbing agent having good water absorbing and holding capacity even against salts, by using a resin obtained by insolubulizing polysaccharide containing uronic acid as a unit for constructing a saceharide by heating and crosslinking as a water absorbing agent.
CONSTITUTION: When a polysaccharide such as xanthane gum or the like containing uronic acid or a salt thereof as a structural unit of the saccharide is swelled by heating, a crosslinked and insolubulized resin is obtained and, thereafter, dried and ground to obtain a water absorbing agent. Thus obtained water absorbing agent has high absorbing and holding capacity for water, as well as even for a salt solution and can be easily prepared in a low cost and easily preserved and disposed.
