"HYDROGEL Highly swellable, cross-linked, hydrophilic, BASED ON MONEMEROS POLIMERIZADOSOU BASED graft polymers, hydrogels PROCESSOPARA PRODUCTION ALTAMENTEINTUMESCiVEIS cross-linked, hydrophilic, and, DEHIDROGeIS USE Highly swellable, cross-linked, hydrophilic". Hydrogels are based on monomerospolimerizados or graft polymer and each has indicede absorptivity under pressure <100 and vertical absorption naomenos than 12 g / g by pressure of 1922.8 Pa. They saoproduzidos hydrophilic monomers via free polimerizacaoradicalmente containing some acid groups or their saisde alkali metal or ammonium, with (a) crosslinking decopolimerizacao containing at least two ligacoesetilenicamente unsaturated double in the molecule, and (b) reactive crosslinker Aque contains the ethylenically unsaturated double bond and pelomenos a functional group capable forming connections covalentescom the acid groups of the hydrophilic polymers, the reticuladorreativo B containing at least two capazesde functional groups forming covalent bonds with the acid groups of polimeroshidrofilicos and / or polyvalent metal ions opcionalmentena presence of at least one base graft to forming opolimer The crosslinked hydrophilic base citadopolimero fragmenting the base and forming the post-crosslinking in dasparticulas surface of said base polymer, and are useful as absorventespara water and aqueous fluids.
