Abstract: The invention relates to stable silicon dioxide dispersions and also their use for producing polyurethanes. The silicon dioxide dispersions are largely or preferably completely free of water and comprise silicon dioxide particles having an average diameter of 1-150 nm and at least one chain extender. The silicon dioxide particles can be modified by means of a silane (S) which comprises groups which are reactive toward isocyanates. Furthermore, a polyol, in particular a polyesterol and/or an isocyanate-comprising compound can be comprised in the silicon dioxide dispersions.
