M2 represents at least one element from the group comprised of Fe(II), Fe (III), Co(III), Cr(III), Mn(II), Mn(III), Ir(III), Rh(III), Ru(II), V(IV), V(V), Co(II) and Cr(II). L1 represents at least one ligand from the group comprised of cyanide, carbonyl, cyanate, isocyanate, nitrile, thiocyanate and nitrosyl. X represents one formate anion, acetate anion or propionate anion. L2 represents one ligand which is mixable with water and from the group comprised of alcohols, aldhydes, ketones, ethers, polyethers, esters, urea derivatives, amides, nitriles and sulfides. a, b, c, d, e, f, g, h, i are whole numbers, whereby a, b, c and d are selected such that the electroneutrality condition is fulfilled and f and g are selected such that the electroneutrality condition is also fulfilled.

Abstract: The invention relates to polyether alcohols that are produced by a ring-opening polymerization of ethylene oxide and at least one alkylene oxide with at least 3 carbon atoms in the molecule to H-functional starting substances. The inventive method is further characterized in that ethylene oxide or a mixture of ethylene oxide and at least one alkylene oxide with at least 3 carbon atoms in the molecule with an ethylene oxide content of at least 98 %, based on the mixture, is added to the starting substance in an amount of maximally 40 % by weight, based on the weight of the polyether alcohol. At least one alkylene oxide with at least 3 carbon atoms in the molecule or a mixture of ethylene oxide and at least one alkylene oxide with at least 3 carbon atoms in the molecule and an ethylene oxide content of maximally 20 % by weight, based on the mixture, is added.

Abstract: In a process for preparing polyether alcohols by catalytic addition of at least two alkylene oxides onto H-functional initiator substances, at least one multimetal cyanide compound is used as catalyst and the addition of the alkylene oxides onto the initiator substance includes incorporation of at least one oxyalkylene block during whose formation at least two alkylene oxides are metered in together and the ratio of the alkylene oxides to one another in the mixture is changed during the joint introduction.

Abstract: The invention relates to a method for producing polyether alcohols by means of catalytic polymerisation of alkylene oxides. Said method is characterised in that the alkylene oxide contains propylene oxide, at least one multimetal cyanide compound is used as a catalyst, and the free alkylene oxide content in the reactor is lower than or equal to 8 wt. %, in relation to the total amount of educts and reaction products in the reactor.
