Abstract

The object of the invention is a method for the dispersion of reactive monomers, wherein a monomer emulsion (8) is fed at a first pressure through a dispersion jet (7) and a second dispersion (9) is fed laterally behind the dispersion jet at a second pressure that is less than the first pressure, both the emulsion and the dispersion being dispersed with one another in a mixing chamber. Using the method, nanoparticle-laden monomer emulsions may be produced that, after polymerization, produce polymer-coated nanoparticles.
