Abstract: A process for preparing a porous material involves at least the steps of providing a mixture (I) containing a composition (A), which contains components suitable to from 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. The composition (A) contains a catalyst system (CS), which contains at least a catalyst component (C1) selected from ammonium salts and phosphonium salts, and an acid with a phosphor containing acid group as a catalyst component (C2). Porous materials can be obtained in this way and the porous materials can be used as thermal insulation material and in vacuum insulation panels and vacuum insulation systems, in particular in interior or exterior thermal insulation systems as well as for insulation of refrigerators and freezers and in water tank or ice maker insulation systems.

Abstract: 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 compound (af) comprising phosphorous and at least one functional group which is reactive towards isocyanates. 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 as well as in water tank or ice maker insulation systems.

Abstract: A molding based on a monolithic organic aerogel has a density in the range from 60 to 300 kg/m3 and a thermal conductivity in the range from 12 to 17.8 mW/m*K. The molding based on a monolithic organic aerogel has more than 30 vol.-% of pores with a diameter of less than 150 nm, and more than 20 vol.-% of pores with a diameter of less than 27 nm, based on the total pore volume. A process can be used to prepare the molding by compression.

Abstract: The present invention relates to a process for preparing a porous material, at least 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 a catalyst (C) selected from the group consisting of alkali metal and earth alkali metal salts of a saturated or unsaturated monocarboxylic acid with 4 to 8 carbon atoms. 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.
