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.
AbstractList 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.
