Abstract (en)
[origin: WO9712575A1] An absorbent material having substantially improved liquid permeability such that it is not subject to gel blocking while maintaining preferred absorbent capacity. The absorbent material comprises (a) a plurality of absorbent gelling particles comprising a water-insoluble, absorbent, hydrogel-forming polymer; and (b) a polycationic polymer covalently bonded to the absorbent gelling particles; wherein the absorbent material has a Saline Flow Conductivity, greater than (500-11.5 . GV)(10<-7>)cm<3>sec/g, wherein GV is the gel volume of the absorbent material.
