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.

摘要： The present invention relates to a polyether carbonate polyol made by copolymerizing a starter molecule with carbon dioxide, at a pressure ranging from about 10 psia to about 2,000 psia, and an alkylene oxide, at a temperature ranging from about 50° C. to about 190° C. and in the presence of from about 0.001 wt. % to about 0.2 wt. % of a substantially non-crystalline double metal cyanide (DMC) catalyst, wherein the polyol has an incorporated carbon dioxide content of from about 1 wt. % to about 40 wt. %, wherein the ratio of cyclic carbonate by-product to total carbonate is less than about 0.3 and wherein the weight percentages are based on the weight of the polyol. The inventive polyether carbonate polyols may find use in producing polyurethane foams, elastomers, coatings, sealants and adhesives with improved properties.
