ABSTRACT:
Particulate, absorbent, polymeric compositions comprising interparticle crosslinked aggregates. The interparticle crosslinked aggregates comprise precursor particles of substantially water-insoluble, absorbent, hydrogel-forming, polymer material; and an interparticle crosslinking agent reacted with the polymer material of the precursor particles to form crosslink bonds between the precursor particles. Sufficient interparticle crosslinked aggregates are formed when the mass average particle size of the resultant polymeric composition has been increased by at least about 25% over the mass average particle size of the precursor particles. The resultant polymeric composition provides improved structural integrity, an increased acquisition rate, and minimal gel blocking properties.
