Abstract
UN METODO PARA LA PRODUCCION DE UN POLISACARIDO QUE AUMENTA DE VOLUMEN CON EL AGUA, GENERALMENTE INDISOLUBLE EN AGUA CON UNAS BUENAS PROPIEDADES DE ABSORCION. EL METODO CONSISTE EN FORMAR UNA MEZCLA DE UN POLISACARIDO MODIFICADO, AGUA Y UN AGENTE ENTRECRUZADOR, RETIRAR EL POLISACARIDO MODIFICADO DE LA MEZCLA Y TRATAR TERMICAMENTE DICHO POLISACARIDO MODIFICADO RETIRADO. TAMBIEN SE DESCRIBE UN POLISACARIDO MODIFICADO QUE TIENE ENTRECRUZAMIENTOS FORMADOS MEDIANTE ESTERIFICACION Y AMIDACION.
