Absorbent members incorporating 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. The absorbent members of the present invention can comprise a combination of fiber material and discrete particles of the polymeric composition or laminates (layered absorbent members) containing such polymeric compositions. The performance of absorbent members is enhanced by the use of such polymeric compositions due to the high rate of fluid uptake and minimal gel blocking properties of the interparticle crosslinked aggregates.

Des éléments absorbants comprenant des compositions polymères particulaires et absorbantes qui sont composées d'agrégats réticulés interparticulaires sont décrits. Les agrégats réticulés interparticulaires comprennent des particules précurseurs de matériau polymère absorbant, formant un hydrogel et pratiquement insoluble dans l'eau; et un agent de réticulation interparticulaire qui est amené à réagir avec le matériau polymène des particules précurseurs pour former des liaisons réticulées entre lesdites particules. Les éléments absorbants de cette invention peuvent comprendre une combinaison de matéraux fibreux et de particules discrètes de la composition polymère ou des éléments laminés (des éléments absorbants disposés en couches) contenant de telles compositions polymères. L'efficacité des éléments absorbants est accrue grâce à l'utilisation de telles compositions polymères en raison du taux élevé d'absorption de fluide et des proprietés réduites de blocage de gel des agrégats réticulés interparticulaires.
