The invention relates to a method for the production of polyether alcohols b y catalytic addition of at least two alkylene oxides to H-functional starting materials. Said method is characterised in that at least one multi-metal cyanide compound is used as catalyst and in the course of the addition to the starting material at least one oxyalykylene unit is incorporated, during which a common dosing of at least two alkylene oxides occurs, whereby during said common dosing the ratio of the amounts of alkylene oxides to each other is varied.
