SOLUTION: The present invention is a method for producing a porous material, the step of providing a composition (A) containing a component suitable for forming an organic gel and a mixture (I) containing a solvent (B), said solvent. The step of reacting the components in the composition (A) to form a gel in the presence of (B), and the step of drying the gel obtained in step b) (where, the composition (A) is , A catalyst system (CS) containing at least a catalyst component (C1) selected from the group consisting of ammonium salts and phosphonium salts, and an acid containing a phosphorus-containing acid group as a catalyst component (C2)). Regarding the method. The present invention also relates to the porous materials thus obtained, and as insulation and in vacuum insulation panels and vacuum insulation systems, especially in internal or external insulation systems, and for insulation of refrigerators or freezers. Also relating to the use of porous materials in insulation systems in water tanks or ice makers. [Selection diagram] None |
