Abstract

UN METODO PARA MODIFICAR ALGINATOS U OTROS COMPUESTOS QUE CONTIENEN ACIDO URONICO, EN EL QUE LOS ALGINATOS O LOS OTROS COMPUESTOS, EN FORMA SOLIDA, SE TRATAN CON CO2 EN CONDICIONES SUPERCRITICAS O PROXIMAS A ELLAS. ENTRE LOS COMPUESTOS QUE PUEDEN TRATARSE, PARA SU EPIMERIZACION, FIGURAN LOS MONO-, OLIGO- Y POLI-URONIDOS, TALES COMO HEPARINA Y SULFATO DE CONDROITINA, ASI COMO OTROS POLIMEROS QUE CONTENGAN URONATOS. EL INVENTO ES UTIL PARA MEJORAR LAS PROPIEDADES FISICAS DE LOS COMPUESTOS TRATADOS.
