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.
La présente invention concerne un procédé de dispersion de monomères réactifs, selon lequel une émulsion de monomères (8) traverse à une première pression une buse de dispersion (7), et une seconde dispersion (9) est introduite latéralement derrière la buse de dispersion, à une seconde pression inférieure à la première pression, et les deux dispersions sont dispersées l'une avec l'autre dans une chambre de mélange. Ce procédé permet de préparer des émulsions de monomères chargées de nanoparticules, qui permettent d'obtenir, après polymérisation, des nanoparticules à revêtement polymère.
