Starter compounds are alkoxylated in a multi-step process. A first alkoxylation step is performed in the presence of certain phosphorus catalysts, to produce an intermediate having a molecular weight of 400 to 1500 g/mol. A second alkoxylation step is performed in the presence of a double metal cyanide catalyst. Residues of the phosphorus catalyst(s) can be left in the intermediate and be present during the second alkoxylation step, so expensive finishing steps can be avoided between the two alkoxylation steps.
