Abstract: Polyethers are prepared by polymerizing an alkylene oxide in the presence of a starter, an aluminum compound that has at least one hydrocarbyl substituent, and a phosphorus-nitrogen base. The phosphorus-nitrogen base is present in only a small molar ratio relative to the amount of starter. The presence of such small amounts of phosphorus-nitrogen base greatly increases the catalytic activity of the system, compared to the case in which the aluminum compound is used by itself. The product polyethers have low amounts of unsaturated polyether impurities and little or no unwanted high molecular weight fraction. Polymers of propylene oxide have very low proportions of primary hydroxyl groups.

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: A method of manufacturing a poly(ether-carbonate) polyol comprises a polymerization stage that includes polymerizing carbon dioxide and at least one alkylene oxide, with a starter, in the presence of a double metal cyanide polymerization catalyst and a catalyst promoter that is devoid of halide anions and cyanide. The catalyst promoter is separate from the double metal cyanide polymerization catalyst.

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.
