Abstract: Preparation of polyisocyanate (I) containing biuret group comprises mixing di- and/or polyisocyanate; water and/or water vapor as biuret-forming agent; optionally catalyst under release of carbon dioxide, in a mixing device with an energy of at least 0.05x10 6> J/kg water (vapor) and leading the obtained reaction mixture into an reactor, in which the reaction mixture, water (vapor) and carbon dioxide are lead in direct or indirect current. An independent claim is also included for a device comprising at least one mixing device, in which around a circulation pump, in which isocyanate directly or unitely with catalyst, water (vapor), optionally inert gas led over inlets, where circulation cycle ends in a promoted product in a downstream cascaded agitating reactor with 2-10 agitated segments, and followed by at least one tranquillizing zone to gas-liquid separation.

Abstract: Continuous method for partial oligomerisation of isocyanates comprises using at least a catalyst (a), which exhibits a content of hydrolyzable halogen of less than 1 wt.%. An independent claim is also included for a preparation of polyisocyanate comprising reacting tertiary amine with an epoxide or an alkyl or a aralkylhalogenide, -sulfate or -carbonate; optionally purifying the obtained reaction mixture with a total content of halogen of less than 1 wt.%; optionally dissolving or dispersing the obtained reaction mixture with a solvent; mixing the quaternary ammonium salt from the above steps with at least an isocyanate; converting the obtained reaction mixture; terminating the reaction; and distillatively purifying the obtained reaction mixture for separating the reacted isocyanate.
