    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.
