Document Type and Number:
WIPO Patent Application WO/1999/003577
Kind Code:
A1
Abstract:
An absorbent composition having a structure comprising a water-absorbing resin (A) and a fine filler (B) contained therein, characterized by having a specific surface area larger by at least 10 % than that of the water-absorbing resin (A) not containing the fine filler (B); and a process for producing the absorbent composition involving the step of drying a polymer in an aqueous gel form to produce a water-absorbing resin (A), after a fine filler (B1) having a true density of 0.1 g/cm?3¿ or lower and a particle diameter of 1 to 200 $g(m)m is incorporated into the polymer.
