  • Isocyanate-reactive compounds from TDI distillation residue and polyurethanes prepared therefrom
    Patent number: 4489177
    Abstract: Isocyanate-reactive compounds are prepared by the reaction of TDI distillation residue with a polyol in such proportions as to obtain a reaction product having an OH-number (mg KOH/g) of about 200 to about 700. The TDI distillation residue is obtained from the distillation of the product of phosgenating toluene diamine to the corresponding toluene diisocyanate and has a toluene diisocyanate content of about 30% to about 70% by weight. The isocyanate-reactive compounds are useful in polyurethane formulations.
    Type: Grant

  • Isocyanate-reactive compounds from modified TDI distillation residue intermediates and polyurethanes prepared therefrom
    Patent number: 4480081
    Abstract: Isocyanate-reactive compounds are prepared by the reaction of a modified TDI distillation residue intermediate with a polyol. The modified TDI distillation residue intermediate is the reaction product of TDI distillation residue with a monohydroxylic compound. The isocyanate-reactive compounds are useful in polyurethane formulations.

  • Process for the preparation of aromatic carbodiimides
    Patent number: 4263221
    Abstract: A process for preparing select symmetrical, aromatic carbodiimides by reacting select symmetrical, aromatic ureas with phosgene in an inert liquid reaction medium. The aromatic carbodiimides produced are useful as components in the preparation of cellular and noncellular polyurethanes, and they can also be used as components in the preparation of isocyanate compositions.
