Zusammenfassung:The present invention relates to a process for preparing autocatalytic polyether alcohols by reacting H-functional starter substances containing at least one amino group which is catalytically active in the urethane reaction, in particular a tertiary amino group, and at least one group which is reactive toward alkylene oxides, in particular a primary and/or secondary amino group and/or hydroxyl group, with alkylene oxides, which comprises a) dissolving the starter substance in a solvent, b) reacting the solution with alkylene oxides.
