摘要

"Hydrogel highly intumescu00ecvel, reticulu00e3do, hidrofilico, based on monu00c8meros polimerizadosou based on polu00ecmeros of graft, processopara production of hidrogu00e9is altamenteintumescu00ecveis crosslinking.Hidrofu00eclico, and use dehidrogu00e9is highly intumescu00ecveis, crosslinked, hidrofu00eclicos ".The hidrogu00e9is are based on monu00f3merospolimerizados or polymer graft and each has u00ecndicede absortividade under pressure 100 and absorption of vertical nu00e3omenos than 12 g / G by pressure.Of 1922,8 pa.They su00e3oproduzidos through hidrofilicos monomers containing certain groups of polimerizau00e7u00e3oradicalmente free acids or their alkali metal or ammonium saisde,With (the) reticulador decopolimerizau00e7u00e3o which contains at least two pairs ligau00e7u00f5esetilenicamente unsaturated fat in the molecule.And (b) reticulador reagent that contains the unsaturated double bond etilenicamente and "at least a functional group capable of forming links covalentescom the acid groups of hydrophilic polymers.The reticuladorreativo B which contains at least two functional groups form covalent linkages capazesde with the acid groups of the polu00edmeroshidrofu00edlicos,And / or with polyvalent metal ions opcionalmentena presence of at least one the basis of graft to form opolu00edmero cross-linked hydrophilic base.Breaking down the citadopolu00edmero base and forming the post crosslinking of the polymer on the surface daspartu00edculas basis, and are useful as absorventespara water and aqueous fluids.
