Abstract
The invention relates to microcapsules made of a core which contains at least one rubber additive and of a shell made of a first polymer. At least one coating made of a second polymer, which differs from the first polymer, and/or of a low molecular inorganic or organic compound, is deposited on the surface of the microcapsules as sliding or wearing layer in order to reduce the static friction.
