Abstract

SE REFIERE A UN METODO PARA LA PRODUCCION DE UN MATERIAL DE ABSORCION ALTAMENTE ABSORBENTE BASADO EN POLISACARIDO, DONDE UNA SOLUCION LIQUIDA QUE CONTIENE UNA MATERIA PRIMA EN FORMA DE UN POLIMERO RETICULABLE BASADO EN POLISACARIDO SE SOMETE A RETICULACION, ANADIENDO UN AGENTE DE RETICULACION COVALENTE A LA SOLUCION POLIMERICA, PARA PRODUCIR UN GEL DILATADO POR LIQUIDO QUE ES SECADO POR EXTRACCION CON UN SOLVENTE POLAR TAL COMO ETANOL, ACETONA O ISOPROPIL. TIENE APLICACION EN LA FABRICACION DE ARTICULOS ABSORBENTES DESTINADOS A LA ABSORCION DE FLUIDOS CORPORALES TALES COMO: PANALES, PROTECTORES PARA INCONTINENCIA Y SIMILARES
