Title (DE) VERFAHREN ZUR HERSTELLUNG WASSERABSORBIERENDER POLYMERPARTIKEL
(EN) METHOD FOR PRODUCING WATER-ABSORBING POLYMER PARTICLES
(FR) PROCÉDÉ DE FABRICATION D'ARTICLES EN POLYMÈRE ABSORBANT L'EAU
Abstract: front page image
(DE)Verfahren zur Herstellung wasserabsorbierender Polymerpartikel durch Polymerisation einer wässrigen Monomerlösung oder -Suspension, mit mindestens einem ethylenisch ungesättigten, sauregruppentragenden Monomer, das durch Zugabe eines Neutralisierungsmittels zumindest teilweise neutralisiert wird, wobei das Neutralisierungsmittel vor der Zugabe filtriert wird.
(EN)The invention relates to a method for producing water-absorbing polymer particles by polymerizing an aqueous monomer solution or monomer suspension, comprising at least one ethylenically unsaturated, acid-group-bearing monomer, which monomer is at least partially neutralized by adding a neutralizing agent, wherein the neutralizing agent is filtered before being added.
(FR)L'invention concerne un procédé de fabrication d'articles en polymère absorbant l'eau par polymérisation d'une solution ou d'une suspension aqueuse de monomère(s), comprenant au moins un monomère insaturé éthylénique porteur de groupes acides. Le monomère est au moins partiellement neutralisé par l'ajout d'un agent neutralisant ; cet agent neutralisant est filtré avant d'être ajouté.
