Abstract

Un polisacarido superabsorbente puede obtenerse al degradar un polisacarido o derivado del mismo con por lo menos 1% en peso de un separador flexible que tiene una longitud de cadena de por lo menos 9 atomos en la cadena y que tiene grupos de acoplamiento activados terminales. El separador flexible puede comprender polialquilenglicol con un peso molecular de aproximadamente 400 a 10,000. Los grupos de acoplamiento pueden proporcionarse por propiedades de divinilsulfona.
