摘要：
The present invention relates to an absorbent article containing a particulate superabsorbent polymer composition having improved stability comprising a polymer comprising from about 0.01 wt % to about 5 wt % of a neutralized aluminum salt solution applied to the surface of a particulate superabsorbent polymer wherein an aqueous solution of the neutralized aluminum salt has a pH value from about 5.5 to about 8 and the particulate superabsorbent polymer composition has a mean particle size distribution of from 300 to 400 μm, an original Free Swell Gel Bed Permeability (FSGBP) of about 20×10−8 cm2 to about 200×10−8 cm2 and a compressibility of from about 1.30 cm2/N to about 4 cm2/N and the particulate superabsorbent polymer composition has a permeability stability index of from about 0.60 to about 0.99 and having particles having a particle diameter of larger than 600 μm in an amount of less than about 15 wt % of the particulate superabsorbent polymer composition.
