ABSTRACT:
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.
