    摘要: 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 and also water 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.

    摘要: The invention relates to a xerogel comprising from 30 to 90% by weight of a monomer component (a1) composed of at least one polyfunctional isocyanate and from 10 to 70% by weight of a monomer component (a2) composed of at least one polyfunctional aromatic amine, at least one of which is selected from 4,4′-diaminodiphenylmethane, 2,4′-diaminodiphenylmethane, 2,2′-diaminodiphenylmethane and oligomeric diaminodiphenylmethane, where the sum of the % by weight of monomer components (a1) and (a2) adds up to 100% by weight and where the monomer components are present in polymeric form in the xerogel and the volume-weighted mean pore diameter of the xerogel is at most 5 μm, The invention further relates to a process for preparing xerogels, to the xerogels thus obtainable and to the use of the xerogels as an insulating material and in vacuum insulation panels.
