Abstract

METODO DE PREPARAR UN HIDROGEL O MATERIAL FORMADOR DE HIDROGEL PARCIALMENTE NEUTRALIZADO Y LIGERAMENTE RETICULADO. CONSISTE EN: A) PREPARAR UNA MEZCLA DE REACCION CONSTITUIDA POR 5 A 35 POR CIEN EN PESO DE MONOMEROS QUE CONTIENEN GRUPOS ACIDOS INSATURADOS Y POLIMERIZABLES EN LA FORMA DE ACIDO LIBRE, DE 0,001 POR CIEN EN MOLES DE UN AGENTE DE RETICULACION Y DE 0 A 5 POR CIEN EN UN INICIADOR DE RADICALES LIBRES EN UN MEDIO ACUOSO; B) SOMETER LA MEZCLA DE REACCION ACUOSA A CONDICIONES DE POLIMERIZACION, PARA PRODUCIR EN AQUELLA UN MATERIAL POLIMERO INSOLUBLE EN AGUA; Y C) NEUTRALIZAR UNA PORCION DE LOS GRUPOS ACIDOS DEL MATERIAL POLIMERO FORMADO EN LA MEZCLA DE REACCION ACUOSA CON CATIONES FORMADORES DE SAL PARA FORMAR UN MATERIAL POLIMERO PARCIALMENTE NEUTRALIZADO EN UN GRADO DE 25 POR CIEN. TIENE UTILIDAD PARA FABRICAR PAÑALES, COMPRESAS Y SIMILARES. R
