  Process for the preparation of modified zinc oxide nanoparticles, which comprises reacting zinc oxide nanoparticles, which are dissolved in a solvent, in the presence of ammonia or amines with a tetraalkyl orthosilicate and optionally with an organosilane, with the proviso that the reaction takes place at a content of less than 5% by weight of water, based on the total amount of solvent and water. Modified zinc oxide nanoparticles which have Si—O-alkyl groups and are soluble in organic solvents, obtainable by this process for the preparation. Liquid or solid formulations which comprise modified ZnO nanoparticles. Inanimate organic materials, for example plastics or coatings, which comprise modified ZnO nanoparticles. Method of stabilizing inanimate organic materials against the effect of light, free radicals or heat, where modified ZnO nanoparticles, which optionally comprise UV absorbers and/or stabilizers as further additives, are added to the materials.

  The polyacetal resin composition contains about 0.01-10 parts by weight of a glyoxyldiureide compound per 100 parts by weight of polyacetal resin. The glyoxyldiureide compound includes glyoxyldiureide and its derivatives (metal salts etc.). Optionally, about 0.01-10 parts by weight of a basic nitrogen-containing compound is further added. The basic nitrogen-containing compound includes melamine, melamine resin, and polyamide resin. Further, an antioxidant may be further added. The above composition contributes to stability, particularly heat stability, of polyacetal resin and suppression of emission of formaldehyde.
