Abstract: Preparation of polyether alcohol (I) comprises reacting at least an alkyl oxide with at least an unsaturated compound (a) having at least an active hydrogen atom per molecule, in the presence of a basic catalyst, where the alkoxylation is carried out in at least two steps. Preparation of polyether alcohol (I) comprises reacting at least an alkylene oxide with at least an unsaturated starting compound (a) having at least an active hydrogen atom per molecule, in the presence of a basic catalyst, where the alkoxylation is carried out in at least two steps, in which the first step is carried out by alkoxylating (a) with a maximum of 35 moles of the alkylene oxide per mole of (a) with a catalyst concentration of a maximum of 0.0085 moles of the basic catalyst per mole, and the second step or the following steps are carried out by alkoxylating (a) obtained from the first step with further alkylene oxide with a catalyst concentration of at least 0.010 mole of the basic catalyst per mole of (a).
