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.
Matériau absorbant présentant une perméabilité aux liquides considérablement améliorée, qui n'est pas sujet à la formation d'un barrage par le gel et qui conserve ses capacités d'absorbtion préférentielle. Ce matériau absorbant comprend (a) plusieurs particules de gel absorbant renfermant un polymère non soluble dans l'eau, absorbant et formateur d'un hydrogel; et (b) un polymère polycationique à liaison covalente avec les particules absorbantes gélifiantes; dans des conditions telles que ce matériau absorbant présente une conductivité aux flux salins supérieure à (500-11,5 GV)(10?-7¿)cm?3¿sec/g, formule dans laquelle GV correspond au volume de gel du matériau absorbant.
