2082623 9118042 PCTABS00008 Water-absorbent resin particles comprising a carboxyl containing water-absorbent resin characterized in that the water-absorbent resin is rendered adhesive by the incorporation of a thermoplastic polymer with hydrophilic character. Optionally, a flow control additive is also employed. In another embodiment the invention comprises water-absorbent structures or articles which comprise a woven or nonwoven mass of fibers of a desired shape characterized in that adhesivized water-absorbent resin particles of the invention are bound to the fibers of the woven or nonwoven mass of fibers. The particles must be prepared by blending water-absorbent resin particles containing carboxyl moieties with a thermoplastic resin having hydrophilic character until the mixture no longer flows freely and, optionally, adding to the water-absorbent resin particles and thermoplastic polymer mixture a flow control additive and blending until the mixture flows freely.
