Abstract: Alkylene oxide polymerizations are performed 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 provides several benefits including more rapid catalyst activation, faster polymerization rates and the reduction in the amount of ultra high molecular weight polymers that are formed. The catalyst mixture is unexpectedly useful in making polyethers having low equivalent weights.

Abstract: Alkylene oxides are polymerized in the presence of a catalyst system that includes a double metal cyanide catalyst that is modified with certain metal or semi-metal compounds. At least one additive is present. The additive is an alkali metal, ammonium or quaternary ammonium salt of a monocarboxylic acid having up to 24 carbon atoms; monobasic potassium phosphate, a monobasic ammonium or quaternary ammonium phosphate, a dibasic ammonium and quaternary ammonium phosphate or phosphoric acid.

Abstract: Polyether diols characterized by a hydroxyl number of 56 or lower, high average functionality and high primary hydroxyl content are prepared by alkoxylating an unsaturated alcohol in multiple steps to form a polyether monol that contains 39% or more primary hydroxyl groups, and then reacting the polyether monol with a mercaptoalcohol that has a primary hydroxyl group.

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 an alkoxylated initiator having a hydroxyl equivalent weight of up to 200. The catalyst remains active, producing a polyol having an equivalent weight of up to 700 with a high oxyethylene content continuously at fast reaction rates.

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.

Abstract: Catalyst complexes include a zinc hexacyanocobaltate with M5 metal and M6 metal or semi-metal phases, wherein M5 metal is gallium, hafnium, manganese, titanium and/or indium and the M6 metal or semi-metal is one or more of aluminum, magnesium, manganese, scandium, molybdenum, cobalt, tungsten, iron, vanadium, tin, titanium, silicon and zinc and is different from the M5 metal. The catalysts are highly efficient propylene oxide polymerization catalysts characterized by rapid activation, short times to the onset of rapid polymerization and high polymerization rates once rapid polymerization has begun.

Abstract: A polyol composition is made by polymerizing a mixture of ethylene oxide and propylene oxide onto a mixture of at least one diol initiator and at least one triol initiator, followed by polymerizing 100% propylene oxide or a mixture of at least 90 weight percent propylene oxide and at most 10 weight percent ethylene oxide. The resulting polyol composition has a hydroxyl equivalent weight of 200 to 400 and an average nominal functionality of 2.05 to 2.95 hydroxyl groups/molecule. 5 to 30 percent of the hydroxyl groups of the coinitiated polyether polyol are primary hydroxyl groups and polymerized ethylene oxide constitutes 40 to 63 percent of the total weight of the coinitiated polyether polyol.
