Abstract
A process for preparing aqueous polymer dispersions by emulsion polymerization of free-radically polymerizable compounds (monomers) comprises adding, during the polymerization of the monomers, a miniemulsion which is an aqueous, surfactant-stabilized emulsion of monomers whose emulsified droplets have a size of from 10 to 500 nm and which comprises a compound (stabilizer) which is dissolved in the monomers of the droplets and whose solubility in the monomers is at least twice its solubility in water.
