摘要：
The invention provides a process for preparing polyoxyalkylene glycol monoethers and/or diethers by reacting an alkoxide with an alkylating agent, which comprises adding water and oligo- or polyethyleneimines which have been alkoxylated with from 1 to 100 C2- to C4-alkylene oxide groups or a mixture of such alkylene oxide groups per free NH group to the mixture of alkoxide, alkylating agent and polyoxyalkylene glycol ether which has formed.
