| titleOfInvention |
Branched polyether carbonate polyols and method for their preparation |
| abstract |
The present invention relates to a process for preparing branched polyethercarbonate polyols comprising the step of reacting an alkylene oxide and carbon dioxide with an H-functional initiator compound in the presence of a catalyst, wherein the reaction is further carried out in the presence of a branching compound having a ring-polymerizable functional group and comprises an H-functional group. The branching compound is added during the reaction such that the proportion of the branching compound in the obtained reaction mixture at any time during the addition is ≦ 7.5% by weight based on the amount of H-functional starter compound, alkylene oxide and branching compound added at this time , The invention furthermore relates to a polyethercarbonate polyol which can be prepared by the process according to the invention and crosslinked polyethercarbonate polymers based thereon. |
