IPC分类号： C08G65/26
摘要： Polyethers are prepared by polymerizing an alkylene oxide in the presence of a double metal cyanide catalyst complex and certain M 5 metal or semi-metal compounds. The double metal cyanide catalyst complex contains 0.5 to 2 weight percent potassium. The ability of this catalyst system to tolerate such high amounts of potassium permits the catalyst preparation procedure to be simplified and less expensive.

摘要： Polyether polyols are prepared by polymerizing unsaturated monomers in a continuous phase of a base polyol. A macromer or polymerization produce of such a macromer is present during the polymerization to stabilize the polymer particles as they form. The macromer is a polyether capped with certain unsaturated epoxide compounds.

摘要： Embodiments of the present disclosure are directed to polyether-acetal polyol compositions, more particularly to polyol compositions including a polyether-acetal polyol that can be utilized to form polyurethanes. As an example, a polyurethane formulation can include a polyol composition including a polyether-acetal polyol functionalized with at least one acetal functional group, where the polyol composition has an average hydroxyl functionality from 2 to 8 and a hydroxyl equivalent weight from 150 to 4000, where the portion of the polyether-acetal polyol that is functionalized with the at least one acetal functional group is 1 percent to 40 percent of a total weight of the polyether-acetal polyol, where the polyether-acetal polyol has a primary hydroxyl group content of at least 55 percent, and a polyisocyanate, where the polyurethane formulation has an isocyanate index in a range from 70 to 500.

摘要： 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.

摘要： 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.

摘要： 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.
