| titleOfInvention | Continuous process for the production of powdered polyisocyanate addition products and the powders produced therefrom |
| abstract | The present invention is directed to a continuous process for the production of powdered polyisocyanate addition products in finely divided form which by simultaneouslyn a) mixing a polyisocyanate component, an isocyanate-reactive component and an inert organic medium containing a surfactant, wherein at least one of the components is insoluble in the inert organic medium, in a low shear stator-rotor dynamic mixer operating at speeds of about 300 to 8000 rpm, utilizing a mixing wattage of about 0.05 to 10.0 watts per cubic centimeter and having a mixing volume of at least about 0.1 liters and b) reacting the polyisocyanate component with the isocyanate reactive-reactive component in the inert organic medium to form solid polyisocyanate addition products which can be separated from the inert organic medium to form a powder, the average residence time of the components and the inert organic medium in the dynamic mixer being about 3 to 300 seconds and the overall flow rate through the dynamic mixer being at least about 20 kg/h. n The present inventon is also directed to the powdered polyisocyanate addition products produced by this process. |
