    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a finely porous rigid foam by using an isocyanate as a base material, and further to provide an apparatus for carrying out the method. SOLUTION: This method for producing a finely porous rigid foam by reacting a polyisocyanate with a compound having at least two reactive hydrogen atoms in a hermetically sealed mold comprises (a) introducing a gas to the reactive components under pressure before inserting the reactive components into the mold, (b) pressurizing the mold before, during or after insertion of the reaction mixture, and (c) reducing the pressure in the mold after the insertion of the reaction mixture into the mold and before the hardening of the rigid foam.

    Abstract: PROBLEM TO BE SOLVED: To obtain an isocyanate-based rigid foam having an open-cell type micro pore by making an polyisocyanate react with a compound having a plural ity of active hydrogen atoms capable of reacting with the isocyanate in the presence of a water foaming agent, a catalyst, an auxiliary and an additive. SOLUTION: A polyisocyante is made to react with a compound containing a plurality of hydrogen atoms capable of reacting with an isocyante such as a hydroxyl group-containing ester represented by the formula having a functionally of 2-8 and a molecular weight of 300-8,000 in the presence of water and, if necessary, an organic compound acting as a physical foaming agent, a catalyst, an auxiliary and an additive to produce an open-cell type rigid foam represented by the formula (wherein (m) is 1-15; (n), (p), (r) and (t) are each 0-1; (o), (q), (s) and (v) are each 0-15; (u) is 0-10; X is 1-5; Y is 1-4; Z is 0-3; Zi is 0.1-3; R1 and R3 have each an aliphtic structure not containing a polyalcoholic hydroxyl group; and R2 is a group not containing COOH group of a polycarboxylic acid.

    Abstract: The invention relates to prepolymers which contain isocyanate groups and which can be produced by reacting an isocyanate mixture, said mixture being predominantly comprised of diphenylmethane diisocyanates and polyphenyl polymethylene polyisocyanates, with a maximum proportion of two-core isomers of 74 wt.% with at least 4 functional polyols or with a mixture of polyols having an average functionality of at least 4. The polyols or polyol mixture comprise(s) a hydroxyl value ranging from 200 to 1650 mg KOH/g and an average molar mass of less than 1100 g/mol with an NCO content of at least 30.0 wt.%. In addition, the invention relates to a method for producing these prepolymers which contain isocyanate groups, to their use for producing polyurethanes, and to a method for producing polyurethanes by reacting at least one of the inventive prepolymers which contain isocyanate groups, optionally mixed with additional organic and/or modified organic isocyanates (a), with compounds having at least two reactive hydrogen atoms (b) in the presence of optional expanding agents (c), catalysts (d), optional additional auxiliary agents and/or additives (e).

    Abstract: The invention concerns a foam consisting of at least 70 wt. % of carbon, having an average cell size more than 30 mu m, porosity between 35 % and 99.7 %, a percentage of open cells higher than 90 %, and comprising linking elements between the cells, which, viewed in cross-section, form a triangle with inward-curving sides. Inside the surface of the cross-section, the sum of the surfaces having a cavity constitutes less than 5 % of the total cross-sectional area of the linking elements. The invention also concerns the use of said foams consisting for the major part of carbon in electrical and electrochemical applications, in the form of filtering material, heat insulation material, support material, storage material and as starting material for other transformations. The invention further concerns a method for producing a foam consisting of at least 70 wt. % of carbon, by pyrolizing synthetic foams. Said method is characterized in that the synthetic foams used contain at least 30 wt. % of a polymer material having a nitrogen content higher than 6 wt. %, and having a porosity between 20 and 99 %, as well as a percentage of open cells higher than 1 %.
