Abstract: The invention relates to a method for the production of autocatalytic polyether alcohols by reacting H-functional starting substances containing compounds that containing at least one amino group, more particularly a tertiary amino group, that is catalytically active for the reaction of urethane and at least one group that reacts with alkylene oxides, more particularly primary and/or secondary groups and/or hydroxyl groups with alkylene oxides. The method comprises the following steps: a) dissolving the starting substances in a solvent and b) reacting the solution with alkylene oxides.
