Abstract:
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung wasserabsorbierender Polymergebilde umfassend die Verfahrensschritte: I. Bereitstellen eines unbehandelten, wasserabsorbierenden Polymergebildes (Pu) mit einer gemäß der hierin beschriebenen Testmethode bestimmten Retention von mindestens 35 g/g; II. in Kontakt bringen dieses wasserabsorbierenden, unbehandelten Polymergebildes (Pu) mit einem permeabilitätssteigernden Mittel. Die Erfindung betrifft weiterhin die durch dieses Verfahren erhältlichen wasserabsorbierende Polymergebilde, wasserabsorbierende Polymergebilde, einen Verbund, ein Verfahren zur Herstellung eines Verbunds, einen Verbund erhältlich durch dieses Verfahren, chemische Produkte beinhaltend wasserabsorbierende Polymergebilde oder einen Verbund sowie die Verwendung wasserabsorbierender Polymergebilde oder des Verbunds in chemische Produkten.
(EN) The invention relates to a method for producing water-absorbent polymer entities, said method comprising the following steps: I. an untreated, water-absorbent polymer entity (Pu) with a retention of at least 35 g/g, defined according to the described test methods, is provided; and II. said water-absorbent, untreated polymer entity (Pu) is brought into contact with a permeability-increasing agent. The invention also relates to the water-absorbent polymer entities that can be obtained by said method, to water-absorbent polymer entities, a composite, a method for producing a composite, a composite that can be obtained by said method, chemical products containing water-absorbent polymer entities or a composite, and the use of water-absorbent polymer entities or the composite in chemical products.
(FR) L'invention concerne un procédé permettant de produire des structures polymères absorbant l'eau, qui comprend les étapes suivantes : (I) préparation d'une structure polymère (Pu) non traitée absorbant l'eau présentant une rétention d'au moins 35 g/g, déterminée selon une méthode de test décrite dans la présente invention et (II) mise en contact de ladite structure polymère (Pu) non traitée, absorbant l'eau avec un agent augmentant la perméabilité. L'invention concerne en outre les structures polymères absorbant l'eau pouvant être obtenues selon ledit procédé, des structures polymères absorbant l'eau, un composite, un procédé permettant de produire un composite, un composite pouvant être obtenu selon ce procédé, des produits chimiques contenant des structures polymères absorbant l'eau ou un composite, ainsi que l'utilisation de structures polymères absorbant l'eau ou du composite dans des produits chimiques.
