    摘要: A polymer polyol composition comprising a continuous phase, a disperse phase within the continuous phase, and a dispersant to enhance the stability of the polymer polyol is disclosed. The dispersant is a grafted polyol-polyacrylate dispersant comprised of a isocyanate vinyl monomer/ethylenically unsaturated monomer random copolymer and a polyoxyalkylene polyether, wherein the random copolymer and the polyoxyalkylene polyether are connected through at least one urethane graft site.Methods of preparing the polymer polyol composition and the grafted polyol-polyacrylate dispersant are provided. The polymer polyol compositions have low viscosities as well as high stability and may be prepared with high levels of dispersed vinyl polymer and high styrene:acrylonitrile ratios in the dispersed vinyl polymer. The polymer polyol compositions are useful for the preparation of polyurethanes, particularly polyurethane foams.

    摘要: Very low viscosity polymer polyols having high styrene/acrylonitrile ratios and good stability may be achieved by the use of epoxy resin-modified polyols as dispersants. The epoxy resin-modified polyols useful as dispersants may be made by reacting a polyol initiator having an active hydrogen functionality of 3 to 8 and one or more alkylene oxides with an epoxy resin. It is preferred that all of the epoxy resin-modified base polyol dispersant be initially charged to the reactor, along with part of the base polyol. In this invention, the base polyol is a conventional polyol unmodified with epoxy resin. The use of epoxy resin-modified polyols as dispersants results in polymer polyols having higher styrene contents, and improved stability and viscosity properties.
