Abstract: A process for preparing polyether polyols includes a precipitation step, a recrystallization step, and a reaction step. In the precipitation step, a multimetal cyanide compound is precipitated by reaction of a metal salt with a cyanometalate compound. In the recrystallization step, the multimetal cyanide compound precipitated above is recrystallized by adding further metal salt and/or further cyanometalate compound. The recrystallization forms a multimetal cyanide catalyst compound. In the reaction step, an initiator and one or more alkylene oxide are reacted in the presence of the multimetal cyanide catalyst compound.

Abstract: The invention relates to a method for producing polyether alcohols by catalytically attaching ethylene oxide and propylene oxide to H-functional starting substances. Said method is characterized in that at least one multimetal cyanide compound is used as a catalyst, and a block comprised of an alkylene oxide having at least three carbon atoms in the molecule is attached to the chain end.

Abstract: The invention relates to polyester-polyether block copolymers which can be produced by the catalytically induced attachment of alkylene oxides to H functional starting materials. Said copolymers are characterised in that polyester alcohols are used as the H functional starting materials and multi - metal cyanide compounds are used as the catalysts.
