Zusammenfassung:	LA INVENCION TRATA DE UNOS POLIMEROS RETICULADOS Y QUE ABSORBEN LIQUIDOS ACUOSOS, SINTETIZADOS A PARTIR DE MONOMEROS SEMINEUTRALIZADOS, QUE CONTIENEN GRUPOS ACIDOS NO SATURADOS MONOETILICAMENTE, ASI COMO, OPCIONALMENTE, OTROS MONOMEROS QUE PUEDEN SER COPOLIMERIZADOS CON LOS ANTERIORES Y, OPCIONALMENTE TAMBIEN, UNOS POLIMEROS ADECUADOS COMO BASE DE INJERTO, Y PRODUCIDOS UTILIZANDO UNOS RETICULADORES COMPUESTOS POR AMINOALCOHOLES NO SATURADOS VARIAS VECES. LOS RETICULADORES UTILIZADOS SON PRODUCTOS DE REACCION DE (MET)ALILAMINAS CON COMPUESTOS MONOGLICIDILOS, COMPUESTOS DI, TRI O TETRAGLICIDILOS Y, OPCIONALMENTE, OXIDOS ALQUILENOS, PRODUCTOS DE REACCION DE (MET)ALILAMINAS O AMINAS PRIMARIAS SATURADAS CON ESTERES (MET)ACRILGLICIDOS Y/O ETERES (MET)ALILGLICIDOS Y, OPCIONALMENTE, OXIDO ALQUILENO. CON LOS POLIMEROS CORRESPONDIENTES A LA INVENCION SE OBTIENEN UNOS SUPERABSORBEDORES, CUYO NIVEL DE PROPIEDAD SE CORRESPONDE CON LOS REQUERIMIENTOS PRACTICOS EN CUANTO A RETENCION, ABSORCION BAJO PRESION, PRESION DE REMOJO Y PERMEABILIDAD PARA LIQUIDOS ACUOSOS. ESTOS POLIMEROS SON UTILIZADOS COMO MEDIOS DE ABSORCION DE AGUA Y LIQUIDOS ACUOSOS EN ESTRUCTURAS USADAS PARA LA ABSORCION DE FLUIDOS CORPORALES, EN CABLES CONDUCTORES DE LUZ O CORRIENTE Y EN LA CRIA DE PLANTAS. PCT No. PCT/EP96/05073 Sec. 371 Date May 20, 1998 Sec. 102(e) Date May 20, 1998 PCT Filed Nov. 18, 1996 PCT Pub. No. WO97/18889 PCT Pub. Date May 29, 1997The present invention relates to cross-linked polymers absorbing aqueous liquids, which are built up of partially neutralized, mono-ethylenically unsaturated, acid groups-containing monomers, optionally further monomers copolymerizable with these, as well as optional polymers suitable as a graft basis, and that can be produced by using cross-linking agents of polyunsaturated amino alcohols. The used cross-linking agents are reaction products of (meth)allylamines with monoglycidyl compounds, di-, tri- or tetraglycidyl compounds, and optional alkylene oxide; reaction products of (meth)allylamines or saturated primary amines with (meth)acrylglycide esters and/or (meth)allyl glycidyl ethers and optional alkylene oxide; as well as reaction products of di- and polyamides with (meth)allyl glycide esters and/or (meth)acrylglycide esters and optional alkylene oxide. The polymers according to the present invention provide superabsorbers whose property level meets the practice-oriented requirements with respect to retention, absorption under pressure, swelling pre
