| titleOfInvention | Process for preparing polyether carbonate polyols |
| abstract | The invention relates to a process for preparing polyether carbonate polyols by adding cyclic propylene carbonate onto an H-functional starter substance in the presence of a catalyst, characterized in that as a catalyst at least one compound according to the formula M n X (I), in which M is selected from the alkali metal cations Li + , Na + , K + and Cs + , X is selected from the anions VO 3 - , WO 4 2- , MoO 4 2- and VO 4 3- , n is 1 if X = VO 3 - , n is 2 when X = WO 4 2- or MoO 4 2- , n is 3 if X = VO 4 3- , is used. |
