Abstract:
1. Polysiloxane nanoparticles, prepared from silazanes or open-chained or cyclic polysilazanes in an alkaline environment, comprising: an average particle size d a specific surface area A a pore volume of at least 0.2 cm an average pore diameter d wherein the nanoparticles have carbon-containing groups, at least some of which are bonded to the silicon in the form of unsubstituted or substituted alkyl or alkenyl groups, wherein the nanoparticles have a portion of, on average, a maximum of 3.5 carbon atoms per silicon atom and wherein to not more than 80% of the silicon atoms, more than one carbon atom is directly bonded, the nanoparticles being meltable.
