ABSORBENT STRUCTURES WITH GELLING AGENT AND ABSORBENT ARTICLES CONTAINING SUCH STRUCTURES ABSTRACT OF THE DISCLOSURE The present invention relates to absorbent structures and absorbent gelling agent compositions suitable for use in disposable absorbent articles such as diapers, incontinence products and catamenial products. The absorbent structures comprise hydrophilic fiber material and nonfragile particles of polymeric gelling agent. The gelling agent particles incorporated into such structures are selected to have a mass median particle size ranging from about 400 to 1680 microns, preferably with the amounts of very large and very small particles kept below certain minimum concentrations. Absorbent structures utilizing gelling agent particles of such particle size characteristics possess unexpectedly high absorbent capacities and the gelling agent therein can be utilized very efficiently and effectively.
