| titleOfInvention | Higher functional polyether carbonate polyols obtained using branching molecules |
| abstract | The present invention relates to a method for producing higher functional polyether carbonate polyols, said method preferably comprising the steps of (α) providing a DMC catalyst and: (αα) a suspending agent that does contain any H-functional groups and/or (αβ) an H-functional starter compound (β) adding carbon dioxide and at least one alkylene oxide (γ) adding carbon dioxide and at least two alkylene oxides, wherein these alkylene oxides can be the same as or different from the alkylene oxide or alkylene oxides added in step (β), and (δ) adding carbon dioxide and at least one alkylene oxide, wherein this alkylene oxide or these alkylene oxides can be the same as or different from the alkylene oxides added in steps (β) and (γ), at least one of the alkylene oxides in step (γ) having an epoxy functionality of ≥ 2 and, in addition, in the case that no H-functional starter compound is provided in (α), step (δ) includes the addition of an H-functional starter compound. |
