Beschreibung
Zusammenfassung:	The present invention relates to a process for preparing a porous material, at least comprising the steps of providing a mixture (I) comprising a composition (A) comprising components suitable to form an organic gel and a solvent (B), reacting the components in the composition (A) in the presence of the solvent (B) to form a gel, and drying of the gel obtained in step b), wherein the composition (A) comprises at least one monool (am). The invention further relates to the porous materials which can be obtained in this way and the use of the porous materials as thermal insulation material and in vacuum insulation panels, in particular in interior or exterior thermal insulation systems. La présente invention concerne un procédé de préparation d'un matériau poreux, comprenant au moins les étapes consistant à utiliser un mélange (I) comprenant une composition (A), comprenant des constituants appropriés pour former un gel organique, et un solvant (B), à faire réagir les constituants dans la composition (A) en présence du solvant (B) pour former un gel et à sécher le gel obtenu dans l'étape b), la composition (A) comprenant au moins un monool (am). L'invention concerne en outre les matériaux poreux qui peuvent être ainsi obtenus et l'utilisation des matériaux poreux comme matériau d'isolation thermique et dans des panneaux d'isolation sous vide, en particulier dans des systèmes intérieurs ou extérieurs d'isolation thermique.
