    • 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 G1 by means of which G can be chemically bonded to the surface of the carrier particles, and wherein G additionally contains reactive groups G2 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 G1 and G2 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.
    • 本发明涉及一种生产聚氨酯泡沫的方法,包括在发泡剂和颗粒存在下多异氰酸酯与多元醇的反应。 这些颗粒是通过使载体颗粒与官能化试剂G反应获得的,其中G含有反应性基团G 1,通过该反应性基团G可将G与化合物结合到载体颗粒的表面,并且其中G另外含有反应性基团G 2 >其中在聚氨酯泡沫生产条件下,对多异氰酸酯的NCO基团或多元醇的OH基团或两者均反应,并且其中G 1和G 2可以相同或 不同。 本发明还涉及通过该方法获得的聚氨酯泡沫以及含有这种聚氨酯泡沫的产品。 本发明还涉及含有多元醇和这些颗粒的组合物。 本发明还涉及包含多异氰酸酯和这些颗粒的组合物。 所提及的组合物都可用于制备根据本发明的聚氨酯泡沫。
