The instant invention is directed to an article of manufacture for absorbing liquids. This invention comprises: a superabsorbent structure; and a permeable means for coating the superabsorbent structure. The superabsorbent structure comprises a superabsorbent polymer mixed into a matrix material, the matrix material being selected from the group consisting of cellulose ester, acrylic acid ester, polyvinyl ester, copolymers of the foregoing and combinations thereof. The permeable means is laminated onto the superabsorbent structure.

Superabsorbent structure

The present invention provides super absorbent materials in the form of sheets or fibers made from high melting polymers and having super absorbent polymer material dispersed uniformly throughout. The materials are capable of incorporating large amounts of super absorbent polymer and so demonstrate substantially improved absorbency and retention properties. The superabsorbent materials comprise a matrix material polymer selected from the group consisting of cellulose esters, acrylic acid esters, polyvinyl esters and copolymers of same, particles of superabsorbent material distributed throughout the matrix material and a plasticizer mixed into the matrix material.

Method for immobilizing superabsorbent polymer and products derived

A method for the manufacture of an absorbent material containing a superabsorbent polymer is disclosed herein. The processing steps include: providing a matrix material in a suitable solvent; mixing particles of a superabsorbent polymer into said solutioned matrix material to form a suspension; homogenizing the suspension; and removing the solvent from the suspension.

Method for immobilizing superabsorbent polymers by homogenization of a
