    摘要: A process for production of an abrasive foam based on a melamine-formaldehyde condensate comprising inorganic nanoparticles, comprising the steps of: (1) preparation of a solution or dispersion comprising a precondensate of the foam to be produced, and also comprising inorganic nanoparticles, (2) foaming of the precondensate via heating of the solution or dispersion from step (1), in order to obtain a foam which comprises inorganic nanoparticles, and also, if appropriate, (3) heat-conditioning of the foam obtained in step (2), leads to improved abrasion in the polishing of delicate surfaces.

    摘要: The present invention relates to a method for producing amphiphilic functionalized highly branched melamine-polyamine polymers by condensing melamine and optionally a melamine derivate having at least one different amine having at least two primary amino groups and optionally also with urea and/or at least one urea derivative and/or with at least one at least difunctional diisocyanate or polyisocyanate and/or at least one carbolic acid having at least two carboxyl groups or at least one derivative thereof, optionally quaternizing a portion of the amino groups of the polymer thereby obtained, reacting the polymer thus obtained with at least one compound capable of undergoing a condensation or addition reaction with amino groups, and optionally quaternizing at least part of the amino groups of the polymer obtained in the first step. The invention further relates to the amphiphilic functionalized highly branched melamine-polyamine polymers that can be obtained by the method according to the invention, and to the use thereof as surface active agents.
