C. by a process in which the reaction is started at a pH of from 5.0 to 5.9 and is ended after a pH of from 5.5 to 8.5 has been reached. As a result of monitoring of the pH, the selectivity of the addition reaction of alkylene oxides with the polymers (A) is substantially improved compared with known processes.
