摘要： The present invention relates to a fast particulate superabsorbent polymer composition comprising a polymer comprising 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 subsequent to subjecting the particulate superabsorbent polymer composition to the Processing Test, the particulate superabsorbent polymer composition has a permeability stability index of from about 0.60 to about 0.99, and a compressibility from 1.30mm
2 /N to about 4mm
2 /N as measured by the Compression Test, and wherein the particulate superabsorbent polymer composition may have a Vortex time of from 25 to 60 seconds and absorbency under load at 0.9psi of from 15 to 21g/g.
