초록 ▼

Absorbent structures are disclosed which contain a particulate material composition. The particulate material composition comprised specific, relatively narrow, particle size distributions of superabsorbent hydrogel-forming material particles formed by solution polymerization methods and mixed with inorganic powders. The particles of superabsorbent material are of such size that at least about 70% 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. Standard 170 mesh sieve with 88 micron openings when said particles are tested according to the Sieving Test described herein. The inorganic powder, such as amorphous silica, is intermixed with the particles of superabsorbent material in amount of between about 0.1 to about 5 parts per 100 parts of the particles of superabsorbent material. The absorbent structures of the present invention are useful in disposable absorbent articles such as diapers, adult incontinence pads, and the like.
