ABSTRACT:
A laminated structure in which a superabsorbent material is provided as a layer of discrete discontinuous chunks or elements attached to a continuous porous support layer. The superabsorbent element is provided by saturating a porous substrate with an acrylic acid monomer solution, polymerizing and crosslinking the monomer in the web, and then dicing the monomer/web substrate to produce discrete superabsorbent elements. The superabsorbent elements having various shaped are then affixed to the flexible porous support layer by friction so as to provide the flexible superabsorbent laminated structure.
