Abstract: The present invention relates to a process for producing porous materials in the form of aerogels or xerogels, which comprises reaction of at least one polyfunctional isocyanate with an amine component comprising at least one polyfunctional substituted aromatic amine in the presence of a solvent and a catalyst, with the reaction being carried out in the absence of water. The invention further relates to the aerogels and xerogels which can be obtained in this way and the use of the aerogels and xerogels as insulation material and in vacuum insulation panels.

Abstract: Xerogel comprises: 20-90 wt.% of a monomer component (a1) made of at least one multifunctional isocyanate; and 10-80 wt.% of a monomer component (a2) made of at least one multifunctional aliphatic amine, where: the total weight of the monomer components (a1) and (a2) is 100 wt.%; the monomer components are present in the xerogel in polymer form; and the volume-weighted average pore diameter of the xerogel is not more than 5 mu m. An independent claim is included for producing xerogels, comprising: (a) providing the monomer components (a1) and (a2) in more separate form; (b) fusing the components (a1) and (a2) in the presence of a solvent; reacting the monomer components (a1) and (a2) in the presence of the solvent to a gel; and (c) drying the obtained gel by transferring the liquid contained in the gel into the gaseous condition at a temperature and a pressure below the critical temperature and the critical pressure of the liquid contained in the gel.
