Abstract: The disclosure is a liquid absorbable material comprising a porous formed article possessed of partitioning walls of a cross-linked polymer and continued micropores, characterized in that said material has a density in the range of 0.2 to 1.0 g/cm.sup.3, and (a) that said partitioning walls exhibit a swelling degree to kerosine in the range of 2 to 10, and that said material has an absorption capacity per unit volume, the capacity being at least 4 cm.sup.3 /cm.sup.3 for water, ethanol, toluene and kerosine, respectively, or (b) that said material has an absorption capacity per unit weight, the capacity being at least 10 g/g for water, ethanol, toluene and kerosine, respectively, the liquids being at a temperature not less than the softening point of the cross-linked polymer. The liquid absorbable material can absorb liquids such as water and petroleum quickly and expand with the absorbed liquid.

Abstract: The present invention provides a water absorbent matter which is physically and chemically stable, difficult in shifting and falling-off of a water-absorbent resin particle and from a cellulose fiber, and thereby, has superior water-absorbent properties. A water absorbent matter like this is made by containing a water-absorbent resin particle having an acidic group such as a carboxyl group on the surface, a cellulose fiber, and a cationic high-molecular compound having a weight-average molecular weight of 2,000 or more, so that the water-absorbent resin particle is firmly set on the cellulose fiber by a cationic high-molecular compound in the presence of water.
