| description | The present invention relates to a method for producing polymers that are suitable for absorbing and storing aqueous fluids, and to polymers that can be obtained by this method. The invention further relates to the use of such polymers. The method comprises the following steps: i) cross-linking radical polymerisation in an aqueous liquid of a monomer composition (M) comprising a) at least one monomer A, comprising an ethylenic double bond and at least one neutralisable acid group or a group that can be hydrolysed into a neutralisable acid group, b) optionally one or more co-monomers B, different from the monomers A and having an ethylenic double bond, and c) 0.05 to 10 wt%, relative to the overall quantity of monomers A and B, of at least one cross-linker C, in the presence of at least one polysaccharide-containing substance (S), wherein the weight ratio of the monomer composition (M) to the substance (S) is in the range of 9:1 to 1:9; and ii) at least partial neutralisation of the acid groups and/or hydrolysis of the acid groups that can be hydrolysed into neutralisable acid groups in the polymer obtained in step i); wherein the polymerisation and/or neutralisation is performed in the presence of urea.
Un procedimiento para preparar polimerizados, que son apropiados para absorber y almacenar líquidos acuosos, así como los polimerizados que se obtienen de acuerdo con este procedimiento. También, uso de estos polimerizados. El procedimiento comprende las siguientes etapas: polimerización radicálica reticulante de una composición monomérica M, que comprende a) al menos un monómero A, que presenta un enlace doble etilénico y al menos un grupo ácido neutralizable o un grupo hidrolizable en un grupo ácido neutralizable, b) eventualmente uno o varios comonómeros B distintos de los monómeros A, que presentan un enlace doble etilénico, y c) 0,05 al 10% en peso, referido a la cantidad total de los monómeros A y B, al menos de un reticulante C en presencia de al menos una sustancia S que contiene un polisacárido, en un líquido acuoso en donde la relación en peso de la composición monomérica M a la sustancia S está en el rango de 9: 1 a 1: 9; y al menos neutralización parcial de los grupos ácidos y/o hidrólisis de los grupos hidrolizables en grupos ácidos neutralizables en el polimerizado obtenido en la etapa i.; en donde se lleva a cabo la polimerización y/o la neutralización en presencia de urea. |
