Procedure for the preparation of polyether ethercarbonate polyols |
| abstract |
Process for the preparation of polyether ether carbonate polyols by adding at least one alkylene oxide, at least one cyclic anhydride as well as carbon dioxide to one or more initiating substances with H functionality in the presence of a double metal cyanide catalyst, characterized in that ( α) a suspending agent that does not contain groups with H functionality is arranged in a reactor, and (γ) during the reaction one or more initiating substances with H functionality are dosed continuously in the reactor and are performed simultaneously or sequentially the dosage of one or several alkylene oxides, the cyclic anhydride and possibly carbon dioxide. |
