    • The present invention relates to a process for the production of a polyurethane foam, comprising the reaction of a polyisocyanate and a polyol in the presence of a blowing agent and of particles. These particles are obtained by reacting carrier particles with a functionalising reagent G, wherein G contains reactive groups G by means of which G can be chemically bonded to the surface of the carrier particles, and wherein G additionally contains reactive groups G which, under the conditions of the polyurethane foam production, are reactive towards the NCO groups of the polyisocyanate, or towards the OH groups of the polyol, or both, and wherein G and G may be the same or different. The present invention relates also to a polyurethane foam obtained by this process and to products containing such a polyurethane foam. The present invention relates also to a composition containing a polyol and these particles. The present invention relates also to a composition containing a polyisocyanate and these particles. Both the mentioned compositions can be used to produce a polyurethane foam according to the invention.
