Abstract: Absorbent structures are disclosed which contain specific, relatively narrow, particle size distributions of superabsorbent hydrogel-forming materials. The absorbent structures of the present invention are useful in disposable absorbent articles such as diapers, adult incontinence pads, and the like. The absorbent articles of the present invention comprise a liquid pervious topsheet, a liquid impervious backsheet joined to the topsheet, and an absorbent core positioned between the topsheet and backsheet. At least a portion of the absorbent core comprises particles of substantially water-insoluble, absorbent hydrogel-forming, polymer material formed by solution polymerization methods. The particles of the hydrogel-forming, polymer material are of such size that at least about 80% of said particles, by weight, will pass through a U.S. Standard 50 mesh sieve with 297 micron openings and be retained on a U.S.
