Abstract: Color stabilization of polyisocyanates involves treating the polyisocyanate (optionally together with a solvent) with a peroxide or a hydroperoxide. Independent claims are also included for (1) preparation of a polyisocyanate by catalytic partial trimerization of a diisocyanate to a room temperature-solid polyisocyanate, stopping the reaction, separating off unreacted diisocyanate, mixing the polyisocyanate with a solvent and treating the dissolved polyisocyanate with a peroxide or hydroperoxide; and (2) a mixture of a polyisocyanate and a (hydro)peroxide optionally together with a solvent.

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.
