| titleOfInvention | Preparation process of polyether carbonate polyols with bimetallic cyanide catalysts and in the presence of metal salts |
| abstract | Process for the preparation of polyether carbonate polyols from one or more initiating substances with H functionality, one or more alkylene oxides and carbon dioxide in the presence of a bimetallic cyanide catalyst and in the presence of at least one metal salt, characterized in that (α ) the bimetallic cyanide catalyst, the metal salt and the initiating substance with functionality H or a mixture of at least two initiating substances with functionality H, (β) are activated for activation (β1) in a first activation stage, a first partial amount (based on the total amount of the amount of alkylene oxides used in the activation and copolymerization) of one or more alkylene oxides is added to the mixture resulting from step (α), this addition of the partial amount of alkylene oxide if necessary in the presence of CO2, (β2) in a second activation stage, after reaching the peak of the temperature In the preceding activation stage, a second partial amount (based on the total amount of the amount of alkylene oxides used in the activation and copolymerization) of one or more alkylene oxides is added to the mixture resulting from the step of previous activation, this addition of the partial amount of alkylene oxide may be carried out, if necessary in the presence of CO2, and (γ) one or more alkylene oxides and carbon dioxide are added to the mixture resulting from step (β) ("copolymerization"), using at least one compound selected from the group consisting of alkaline earth halides, alkaline earth carboxylates and aluminum carboxylates as metal salt. |
