Abstract: 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 th e starting material at least one oxyalykylene unit is incorporated, during whi ch 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.

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.

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.

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. Sa id 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.
