摘要：
The invention relates to a method for working up polyether alcohols which may be produced by the catalytic addition of alkylene oxides to H-functional starting materials. Said method is characterised in that at least one multi-metal cyanide compound is employed as catalyst and that the catalyst is separated by sedimentation from the polyether alcohol, after the addition of the alkylene oxide.
