Abstract

LA INVENCION SE REFIERE A UN METODO PARA EL TRATAMIENTO ENZIMATICO DE MATERIALES LIGNOCELULOSICOS QUE CONTIENEN POLIMEROS DE SILANO, TALES COMO PULPAS DE CELULOSA KRAFT. DE ACUERDO CON EL METODO DE LA INVENCION, AL MENOS PARTE DE LOS GRUPOS DE ACIDO HEXENURONICO PRESENTES EN EL MATERIAL SE ELIMINA SELECTIVAMENTE PARA ELIMINAR LOS IONES DE METAL DE LA PULPA, PARA CAMBIAR LA CARGA SUPERFICIAL DE LA MISMA, PARA MEJORAR LA ESTABILIDAD DE BRILLO DE LA PULPA Y PARA DAR COMO RESULTADO UN MATERIAL MAS ADECUADO PARA EL TRATAMIENTO ENZIMATICO.
