FIELD: chemistry.
SUBSTANCE: invention relates to porous gel. Porous gel contains the following components in converted form: (a1) at least one polyfunctional isocyanate, (a2) at least one polyfunctional aromatic amine, selected from the group, including 4,4'-diamino-diphenylmethane, 2,4'-diaminodiphenylmethane, 2,2'-diamino-diphenylmethane and oligomer diaminodiphenylmethane, and (a3) at least one polyalkylenepolyamine, with quantity of (a3) component constituting from 0.01 to 5 wt %, counted per the total weight of components (a1), (a2) and (a3). Also claimed is method for obtaining porous gels, application of porous gels as insulation material and for vacuum insulation panels.
EFFECT: obtaining gels with high porosity and low heat conductivity.
