  • Patent number: 10301419
    Abstract: Random poly(propylene oxide-co-ethylene oxide) polymers are made by polymerizing a mixture of propylene oxide and a small amount of ethylene oxide in the presence of a starter and a double metal cyanide catalyst complex, and then feeding in a mixture of propylene oxide and ethylene oxide while increasing the ethylene oxide concentration in the mixture to at least 90%. This produces a polyol suitable for making high resiliency polyurethane foam without need for adding an ethylene oxide cap.

  • Patent number: 9840579
    Abstract: Thixotropic polyol dispersions are described. The dispersions contain a dispersed phase of polyurethane-isocyanurate particles. They can be made by reacting a low equivalent weight polyol with a polyisocyanate in the presence of an isocyanate trimerization catalyst while dispersed in a base polyol. These polyol dispersions are useful as the resin component of curable systems such as formulated coatings, sealants or adhesives.

  • Patent number: 9840578
    Abstract: PIPA polyols are made in a two-step process. In the first step, a base polyether polyol and a polyisocyanate are reacted to form a mixture that contains unreacted base polyol, unreacted polyisocyanate and adducts of the base polyol and polyisocyanate. A low equivalent weight polyol is then added and reacted in a second step to form the dispersion. The process unexpectedly produces a stable dispersion of the fine PIPA particles in the base polyol, even when the base polyol contains mostly secondary hydroxyl groups. The process also permits the tuning of product viscosity by increasing or decreasing the extent of reaction in the first step.
