Method for processing polyether alcohols

In a process for working up polyether monools which have been prepared by ring-opening polymerization of epoxides by means of OH-functional starters using at least one heterogeneous catalyst, the heterogeneous catalyst or catalysts is/are separated off from the polyether monool by means of a membran...
