Abstract: The present invention relates to a process for the preparation of composites which can be used in the dental field, in which a) mono-or polyfunctional monomers dissolved in a solvent are polymerized to give a polymer gel thoroughly swollen with the solvent, b) the polymer gel produced is subjected to preliminary size reduction, c) a reactive gel is subsequently prepared by the polymer gel, subjected to preliminary size reduction, incorporating a polymerizable monomer or a mixture of polymerizable monomers in the polymer gel while simultaneously removing the solvent, and d) a dental composite is prepared from the reactive gel thus obtained.
