Abstract:
Hybrid microparticle having a polymer core and a shell which surrounds the polymer core at least in sections and which has a silicon dioxide layer; characterized by an RF value, the RF value being defined as the ratio of an external surface area amenable to the adsorption of nitrogen to a surface area which is computable from an arithmetic mean diameter of the hybrid microparticle considered as an ideal sphere, where the shell has a structure selected from: closed and smooth, with the shell having an RF value of between 1 and 1.5; closed and hillocky, with the shell having an RF value of between 1.51 and 3; or open, with the shell having an RF value of greater than 3.01.
