Abstract: A polyurethane reaction system includes an isocyanate component having at least one polyisocyanate and an isocyanate-reactive component having a storage stable polyol component that is a single phase liquid mixture at 23° C. including a first polyether polyol and a second polyether polyol. The first polyether polyol is included in an amount from 20 wt % to 90 wt %, based on total weight of the polyol component, is a glycol based polyoxypropylene-polyoxyethylene polyether polyol having number average molecular weight from 1500 g/mol to 1975 g/mol, and has a polyoxyethylene content from 26 wt % and 34 wt % based on a total weight of the first polyether polyol. The second polyether polyol is included in an amount from 10 wt % to 80 wt %, based on total weight of the polyol component, has a number average molecular weight from 750 g/mol to 4000 g/mol, and has a melting point higher than 23° C.

Abstract: Polymer polyols are made in a seeded process, in which styrene and acrylonitrile are polymerized in the presence of a base polyol, a seed dispersion and a solvent. The seed dispersion contains an unsaturated macromer. The process produces a polymer polyol in which the dispersed phase particles have a particle size of 1 to 3 μm and a particle size span of less than 1.25. The polymer polyols are very useful for making flexible polyurethane foam for cushioning applications, in which high airflows and good load bearing are needed.

Abstract: A method for making a copolymer polyol includes (a) forming a pre-compounded thermoplastic polymeric composition by compounding from 10 wt % to 90 wt % of a solid functional additive component with from 10 wt % to 90 wt % of a polystyrene component, (b) melting the pre-compounded thermoplastic polymeric composition to form a melted thermoplastic polymeric composition, (c) combining the melted thermoplastic polymeric composition with a carrier polyol component in the presence of a stabilizer component to form a pre-mixture that includes the pre-compounded thermoplastic polymeric composition dispersed within a continuous phase of the carrier polyol component, and (d) cooling the pre-mixture to form the copolymer polyol.

Abstract: A preformed thermoplastic polymer is dispersed into a polyol via a mechanical dispersion process. A stabilizer is present to stabilize the dispersed polymer particles. An antisolvent is also present. The antisolvent has been found to lead to smaller particle size and increased dispersion stability.

Abstract: 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.
