Abstract

LA INVENCION TRATA DE UNOS MEDIOS DE ABSORCION EN POLVO PARA AGUA Y LIQUIDOS ACUOSOS BASADOS EN POLIMEROS QUE PUEDEN HINCHARSE CON EL AGUA, PERO QUE NO SE DISUELVEN EN ELLA Y QUE SE ENCUENTRAN RETICULADOS, SIENDO SINTETIZADOS A PARTIR DE MONOMEROS QUE PORTAN GRUPOS ACIDOS SEMINEUTRALIZADOS Y NO SATURADOS MONOETILICAMENTE, ASI COMO, OPCIONALMENTE, OTROS MONOMEROS QUE PUEDEN COPOLIMERIZARSE CON LOS ANTERIORES Y, OPCIONALMENTE TAMBIEN, UNOS POLIMEROS ADECUADOS COMO BASE DE INJERTO. DICHOS POLIMEROS SON PREPARADOS UTILIZANDO UNA COMBINACION RETICULANTE DE I: DE UN 40 A UN 90 % MOLAR DE CH 2 = CHR 5 CO (OCHR 3 CH 3 ) Z O CH 2 CHR 5 = CH 2 , Y II: DE UN 10 A UN 60 % MOLAR DE R 1 [O(CHR 3 CHR SUP,3 O) U CO R 2 ] X , EN DONDE R 1 ES UN A LQUILO C2 10 POLIVALENTE; R 2 ES UN ALQUENILO C2-10 LINEAL O ARBORESCENTE; R 3 ES H, CH 3 , C 2 H 5 ; R5 ES H, CH 3 ; X ES IGUAL A 2-6; U ES IGUAL A 0-15 Y Z ES IGUAL A 3-20. MEDIANTE LA POSTERIOR RETICULACION SUPERFICIAL SE CONSIGUE UNA COMBINACION CARACTERISTICADE GRAN RETENCION Y ELEVADA ABSORCION BAJO PRESION, ADEMAS DE UN NUMERO PEQUEÑO DE COMPONENTES SOLUBLES Y UNA RAPIDA ABSORCION DE LIQUIDOS. LOS POLIMEROS SON UTILIZADOS EN ESTRUCTURAS TALES COMO COMPRESAS PARA LA ABSORCION DE FLUIDOS CORPORALES, EN CABLES CONDUCTORES DE LUZ O CORRIENTE Y EN LA CRIA DE PLANTAS.
