摘要： A process for activating double metal cyanide catalysts is disclosed. A polyol starter or starter/catalyst mixture is heated under vacuum under conditions effective to achieve improved stripping compared with that which can be achieved through conventional vacuum stripping. Coupling vacuum stripping with inert gas sparging or stripping in the presence of an organic solvent gives a starter/catalyst mixture that activates rapidly in an epoxide polymerization process. Rapid activation makes process start-ups reliable and reduces cycle time. The process gives polyols with lower viscosity, lower polydispersity, and lower unsaturation for better polyurethanes.

摘要： Polyacrylate graft-polyols are found to be homogeneous liquids useful as dispersants in vinyl polymer polyols. The novel polyacrylate graft-polyols are made by polymerizing at least one acrylate monomer in a polyol where the resultant polyacrylate is soluble in the polyol used. The polyol may be a polyoxyalkylene polyether polyol. No copolymer or unsaturated polyol is required to make vinyl polymer polyols having high styrene/acrylonitrile ratios, good stability and improved viscosity properties when these polyacrylate graft-polyol dispersants are employed. The vinyl polymer polyols are in turn useful in reactions with polyisocyanates in the presence of suitable catalysts to make polyurethane products.

摘要： Very low viscosity polymer polyols having high styrene/acrylonitrile ratios and good stability may be achieved by the use of epoxy modified polyols as dispersants. The epoxy modified polyols useful as dispersants may be made by one of three methods: (1) adding the epoxy resin internally to the modified polyol, (2) capping or coupling a polyol not containing an epoxy resin with such a resin, and (3) providing the epoxy resin both internally to the polyol and as a cap or coupler. Epoxy modified polyols having a hydroxyl to epoxy ratio of about 8 or less, made by one of these techniques, are superior dispersants and provide polymer polyols having higher styrene contents, and improved stability and viscosity properties. In one aspect, the epoxy modified polyols contain a significant amount of high moleular weight polyol adducts; generally from about 5 to about 30 wt. % of materials having a GPC molecular weight of greater than 100,000; and at least greater than 80,000. Base polyols unmodified with an epoxy resin are used to make the polymer polyols.

摘要： Low viscosity polymer polyol polyols having high styrene/acrylonitrile ratios and good stability may be achieved by the use of a high molecular weight (HMW) dispersant polyol comprising less than 5 wt. % of the total polyol component of the polymer polyol. The HMW dispersant should have a molecular weight higher than about 6000. Preferably, a semi-batch reactor is used, and a relatively high concentration of the HMW dispersant is initially charged to the reactor, relative to the portion of base polyol, which has a molecular weight of less than 4000.
