Abstract
La invención se refiere a polímeros reticulados superabsorbentes para líquidos acuosos, constituídos sobre la base de monómeros monoetilénicamenteinsaturados que llevan grupos ácidos parcialmente neutralizados, eventualmente otros monómeros copolimerizables, así como eventualmente polímeros adecuadoscomo base de injertos y que son capaces de ser preparados mediante una combinación de reticulante y monómero I.CH2=CHR6-CO-(OC HR3-CHR3)zO-CH2-CHR6=CH2;II.CH2=CHR6-R5-(OCHR3-CHR3)vOR4;III.R1-[O(CHR3-CHR3O)u-CO-R2]x y/o di o trialilamina y/o bisacrilamidas; con R1=alquilo C2-C10 polivalente;R2=alquenilo C2-C10 recto o ramificado; R3=H, CH3, C2H5; R4=H, alquilo C1-C10 lineal o ramificado; R5=CO, CH2; R6=H,CH3; x=2-6; u=0-15; v=1-45; z= 3-20. Lospolímeros según la invención presentan con relación al estado del arte una mejor combinación de las propiedades de retención, absorción de líquido bajopresión a 63g/cm2 y proporción de componentes solubles, mayor permeabilidadde la capa de gel para líquidos acuosos y elevada velocidad de succión y elevadapresión de hinchamiento. Los polímeros se aplican como absorbentes para agua y soluciones acuosas en construcciones, para la absorción de líquidos corporales,en cablesconductores de corriente y de fibra óptica y en cultivo de vegetales. La invención también comprende un procedimiento de preparación de dichospolímeros.The invention relates to super absorbent crosslinked polymers for aqueous liquids, based on monoethylenically unsaturated monomers bearing partially neutralized acid groups, optionally other copolymerizable monomers, as well as optionally suitable polymers as graft base and which are capable of being prepared by a combination of crosslinker and monomer I.CH2 = CHR6-CO- (OC HR3-CHR3) zO-CH2-CHR6 = CH2; II.CH2 = CHR6-R5- (OCHR3-CHR3) vOR4; III.R1- [O (CHR3-CHR3O ) u-CO-R2] xy / o di or triallylamine and / or bisacrylamides; with R1 = polyvalent C2-C10 alkyl, R2 = straight or branched C2-C10 alkenyl; R3 = H, CH3, C2H5; R4 = H, C1-C10 linear or branched alkyl; R5 = CO, CH2; R6 = H, CH3; x = 2-6; u = 0-15; v = 1-45; z = 3-20. The polymers according to the invention have, in relation to the state of the art, a better combination of retention properties, absorption of liquid under pressure at 63g / cm2 and proportion of soluble components, greater permeability of the gel layer for aqueous liquids and a high suction speed and high pressure. swelling. The polymers are applied as absorbents for water and aqueous solutions in buildings, for the absorption of body fluids, in current and fiber optic cables and in vegetable cultivation. The invention also comprises a process for preparing said polymers.
