Abstract (en)
[origin: WO0032663A1] Process for preparing polyisocyanate based organic aerogels comprising the steps of a) mixing an organic polyisocyanate and a carbodiimide catalyst and optionally a polyfunctional isocyanate-reactive compound in a solvent, b) maintaining said mixture in a quiescent state for a sufficiently long period of time to form a polymeric gel and c) supercritically drying the obtained gel.
