ABSTRACT:
A method for producing an absorbent structure and the resulting absorbent structure. The method includes the steps of introducing a thermoplastic polymer into an extrusion apparatus, melting the thermoplastic polymer material having a moisture content of at least 0.5 percent by weight into the extrusion apparatus, and extruding the mixture such that the fluid in the superabsorbent polymer material evaporates as pressure is released and induces foaming of the thermoplastic polymer that bonds the particulate polymer material together to create a matrix.
