| titleOfInvention | Methods for forming polycarbonate ether polyols and high molecular weight polyether carbonates |
| abstract | The process for preparing the polycarbonate ether polyol or the high molecular weight polyether carbonate using a controlled addition of materials during the polymerization comprises the steps of: mixing a catalyst of formula (I), a double metal cyanide (DMC) a catalyst and optionally carbon dioxide and / or a solvent with an epoxide and optionally a starting compound and / or carbon dioxide; or mixing the DMC catalyst and optionally the starting compound, the carbon dioxide and / or the solvent with the epoxide and optionally the carbon dioxide and / or the solvent; or mixing the epoxide, the catalyst of formula (I), a starting compound and carbon dioxide and optionally a solvent; or a mixture catalyst of formula (I), a DMC catalyst and optionally a starting compound, an epoxide, a carbon dioxide and / or a solvent to form in each case a mixture (alpha); and adding one or more of the starting compound, the epoxide, the carbon dioxide, the catalyst of formula (I), the DMC catalyst and / or the solvent to the mixture (alpha) to form a mixture (beta) comprising a starting compound, an epoxide, carbon dioxide, a catalyst of formula (I), a DMC catalyst and optionally a solvent. |
