| titleOfInvention | Method for producing high molecular weight polyether polyol |
| abstract | A method for producing a polyether polyol having an equivalent molecular weight of 8,000 to 20,000 g / mol, preferably 9,000 to 20,000 g / mol, particularly preferably 10,000 to 16,000 g / mol. Providing a method optimized to achieve the lowest possible viscosity and the narrowest possible molecular weight distribution. A method for producing a polyether polyol having an equivalent molecular weight of 8,000 to 20,000 g / mol from one or more H-functional starter compounds and one or more alkylene oxides in the presence of a double metal cyanide catalyst. A method in which alkylene oxide is metered into a reactor during 15 to 23 hours. DMC catalyst and one or more H-functional starter compounds are introduced into the reactor, the inert gas is stripped at 60-160 ° C., depressurized to 5-500 mbar, and 1-15 or more over 15-23 hours. A process wherein the alkylene oxide is metered into the reactor. [Selection figure] None |
