<p>Producing porous material, comprises reacting (a1) at least one polyfunctional isocyanate, (a2) at least one polyfunctional substituted aromatic amine (I) and optionally at least one further polyfunctional aromatic amine that is different from the amine (I), and (a3) water, in presence of a (C) solvent and optionally in presence of (a4) at least one catalyst. Producing porous material, comprises reacting (a1) at least one polyfunctional isocyanate, (a2) at least one polyfunctional substituted aromatic amine of formula (I) and optionally at least one further polyfunctional aromatic amine that is different from the amine (I), and (a3) water, in presence of a (C) solvent and optionally in presence of (a4) at least one catalyst. R 1>, R 2> : H or 1-6C alkyl; and Q 1>-Q 5>, Q 1> 1>, Q 2> 1>, Q 3> 1>, Q 4> 1>, Q 5> 1> : 1-12C alkyl (optionally substituted), H or primary amino. Provided that: (I) comprises at least two primary amino groups, where at least one of the groups Q 1>, Q 3>and Q 5>, and at least one of the groups Q 1> 1>, Q 3> 1>and Q 5> 1>are primary amino groups; and the groups Q 2>, Q 4>, Q 2> 1>and Q 4> 1>are selected such that (I) exhibits at least one alkyl group having 1-12C that is optionally substituted, in alpha -position to at least one primary amino group that is bonded to the aromatic ring. An independent claim is also included for the porous material obtainable by the above method. [Image].</p> |
