titleOfInvention |
Continuous process for making polyether polyols having high polymerized ethylene oxide content using a double metal cyanide catalyst complex and a magnesium, group 3 - group 15 metal or lanthanide series metal compound |
abstract |
An alkylene oxide mixture containing greater than 50% by weight ethylene oxide is continuously polymerized in the presence of a double metal cyanide polymerization catalyst and certain magnesium, Group 3-Group 15 metal or lanthanide series metal compounds. The presence of the magnesium, Group 3-Group 15 metal or lanthanide series metal compound permits the polymerization to be performed continuously without premature deactivation of the double metal cyanide catalyst. |
