摘要： The present invention relates to a process for preparing polyether polyols by addition of alkylene oxides onto H-functional starter substances, characterized in that at least one urethane alcohol of formula (II) where R
1 is linear or branched C
2 to C
24 -alkylene which may optionally be interrupted by heteroatoms such as O, S or N and may be substituted, R
2 is linear or branched C
2 to C
24 -alkylene which may optionally be interrupted by heteroatoms such as O, S or N and may be substituted, R
3 is H, linear or branched C
1 to C
24 -alkyl, C
3 to C
24 -cycloalkyl, C
4 to C
24 -aryl, C
5 to C
24 -aralkyl, C
2 to C
24 -alkenyl, C
2 to C
24 -alkynyl, each of which may optionally be interrupted by heteroatoms such as O, S or N and/or each of which may be substituted by alkyl, aryl and/or hydroxyl, is used as H-functional starter compound. The invention further provides the polyether polyols containing a urethane group, the polyether polyols obtainable by the process according to the invention, for the use of the inventive polyether polyols for preparation of a polyurethane polymer, and the resulting polyurethane polymers.
