摘要
The present invention relates to a method for producing polyether carbonate polyols, the polyether carbonate polyols having electron-poor and electron-rich double bonds, said method preferably comprising the steps of (a) providing a suspending agent and/or an H-functional starter compound and a DMC catalyst, 03) adding at least one epoxide and (y) adding carbon dioxide, an epoxide that does not contain an unsaturated group, and at least two unsaturated compounds, the unsaturated compounds in method step (y) being selected from the group comprising unsaturated epoxides and unsaturated cyclic anhydrides, and one of the unsaturated compounds having an electron-rich double bond and one of the unsaturated compounds having an electron-poor double bond. The invention also relates to the crosslinking of polyether carbonate polyols, the polyether carbonate polyols having electronpoor and electron-rich double bonds, and to the crosslinked polyether carbonates obtainable therefrom.
