ABSORBENT MATERIAL HAVING IMPROVED ABSORBENT PERMEABILITY AND METHODS FOR MAKING THE SAME

摘要

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)cm3sec/g, wherein GV is the gel volume of the absorbent material.
