    Abstract: The invention relates to a method for production of organic xerogels comprising: (a) preparation of a composition containing an organic gel precursor (A) and a solvent (C), (b) reaction of the gel precursor (A) in the presence of the solvent (C) to give a gel, (c) modifying the obtained gel by means of at least one organic compound (D), which is not added in step (a) nor in step (b), (d) drying the modified gel by transforming the solvent (C) into the gaseous phase at a temperature and a pressure below the critical temperature and critical pressure of the solvent (C). The invention further relates to the organic xerogels thus obtained and the use thereof as insulation.
