Abstract

En la presente invención, se describe un método simple y nuevo para la síntesis homogénea de éteres de celulosa; los líquidos iónicos no sólo se usan como solvente y como medios de reacción para la eterificación homogénea de celulosa; la celulosa disuelta se trata con el agente de eterificación en ausencia de bases orgánicas o inorgánicas y en ausencia y/o presencia de cantidades moderadas de agua; los éteres de celulosa obtenidos muestran nueva distribución de la sustitución en la cadena de polímero que resulta en nuevas propiedades y aplicaciones.
