ABSTRACT OF THE DISCLOSURE This invention is directed to a method for increasing the gel strength of a water-absorbent composition comprising a water-absorbent amount of a crosslinked water-swellable hydrophilic polymer and an inorganic powder in an amount sufficient to increase the gel strength of the water-absorbent composition. The method is characterized by physically blending the inorganic polymer with the polymer after the polymer has been polymerized and crosslinked. The compositions produced by the method of this invention can be incorporated into applications useful in removing water from numerous systems. -11-
