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: In multimetal cyanide complexes, more than 30% by weight of the primary particles have a platelet-like habit, i.e. the length and width of the primary particles is at least three times the thickness of the particles.

Abstract: The invention relates to a method for producing polyurethanes by reacting at least one polyisocyanate with at least one compound having at least two hydrogen atoms that are reactive with isocyanate groups. The method is characterised in that at least one polyether alcohol is used for the connection to at least two active hydrogen atoms. Said polyether alcohol is produced by adding alkylene oxides to H-functional initiator substances by means of multi-metal cyanide catalysis. The reaction is carried out in the presence of at least one metallic salt.
