    Abstract: The invention relates to a method for the preparation of polyether polyols by catalytic reaction of H-functional initiator substances with lower alkylene oxides. Said method is characterized in that multi-metal cyanide compounds are used as catalysts and butanediol-1,4, alpha -hydroxy- omega -hydroxypoly(oxy-1,4-butanediyl), pentanediol-1,5, decanediol-1,10 or mixtures of at least two of the above compounds are used as H-functional initiator substances.
