Abstract
A process for the preparation of polymer lattices comprising polymer nanoparticles by a photo-initiated heterophase polymerization includes preparing a heterophase medium comprising a dispersed phase and a continuous phase and at least one of at least one surfactant, at least one photoinitiator, and at least one polymerizable monomer. The at least one polymerizable monomer is polymerized by irradiating the heterophase medium with electromagnetic radiation so as to induce a generation of radicals. The at least one photoinitiator is selected from compounds comprising at least one phosphorous oxide group (P═O) or at least one phosphorous sulfide (P═S) group. The irradiating of the heterophase medium is effected so that a ratio of an irradiated surface of the heterophase medium to a volume of the heterophase medium is at least 200 m.
