Abstract
La invencion se refiere a un procedimiento para la produccion de poliéterpolioles mediante poliadicion catalizada con ácidos de oxidos de alquileno a compuestos que exhiben átomos de hidrogeno activos, que se caracteriza porque la poliadicion se lleva a cabo en presencia de sales de ácidos perfluoralquilsulfonicos (perfluoralquilsufonatos) de metales del grupo III A del Sistema Periodico de los Elementos (correspondientes de la Convencion de la IUPAC de 1970), a temperaturas de 40 a 200 degree C a presion normal o a presiones de 0 a 20 barias (absolutas), dado el caso en presencia de un disolvente orgánico inerte y a continuacion, mediante disminucion de la temperatura y/o mediante adicion de un agente precipitante y/o mediante extraccion con agua, se separa prácticamente todo el catalizador de la mezcla de reaccion y, si se desea, se vuelve a utilizar para la reaccion de poliadicion.
