Abstract

Un método para purificar un polímero de poli(óxido de etileno) que contiene una fracción de menor peso molecular y por lo menos una fracción de mayor peso molecular, caracterizado porque comprende:a) mezclar el polímero de poli(óxido de etileno) con un compuesto o con una mezcla de compuestos, siendo dicho compuesto o dicha mezcla de compuestos un solvente para la fracción de bajo peso molecular, pero no para la fracción de elevado peso molecular, en cantidades relativas y bajo condiciones tales, que se forme una solución de bajo peso molecular en el compuesto o la mezcla de compuestos, yb) separar la solución de fracción de elevado peso molecular.
