Abstract

Organopolysiloxane particles consist of a single molecule, are crosslinked, and contain metal atoms in the zero valent oxidation state, the metal atoms in each case being in intermetallic interaction with at least one further metal atom in the zero valent oxidation state, have an average diameter of 5 to 200 nm and are soluble to the extent of at least 0.1% by weight in at least one organic solvent chosen from the group consisting of methylene chloride, pentane, acetone, toluene and ethanol, at least 80% of the particles having a diameter which deviates from the average diameter by not more than 30%.
