Abstract (en)

[origin: WO2007134712A1] The invention relates to nanoparticles, more particularly surface-modified nanoparticles, having an average particle size as determined by means of particle correlation spectroscopy (PCS) or the transmission electron microscope in the range from 3 to 50 nm, in dispersion in an organic solvent, characterized in that they are obtainable by a process in which one or more precursors of the nanoparticles are reacted in an organic solvent with a compound M<SUB>3-x</SUB>[O<SUB>3</SUB>(-)<SUB>x</SUB>SiR<SUB>1-x</SUB>] to give the nanoparticles, x being an integer selected from 0, 1 or 2, M being H, Li, Na or K, and all radicals R, in each case independently of one another, being a branched or unbranched, saturated or unsaturated hydrocarbon radical having 1 to 28 C atoms, in which one or more C atoms may have been replaced by O, and also to their use for UV protection in polymers.
