  • Process for the modification of polymers, in particular polymer nanoparticles
    Patent number: 8921444
    Abstract: A process for the preparation of modified polymers by a photo-initiated polymerization includes preparing a polymerization medium comprising at least one photoinitiator comprising at least one phosphorous oxide (P?O) group or at least one phosphorous sulfide (P?S) group, and at least one polymerizable monomer. The at least one polymerizable monomer is polymerized by irradiating the polymerization medium with electromagnetic radiation so as to induce a generation of radicals so as to obtain a polymer. The polymer is modified by irradiating the polymer with electromagnetic radiation so as to induce a generation of radicals from the polymer in a presence of at least one modifying agent.
    Type: Grant
    Filed: October 17, 2011
    Date of Patent: December 30, 2014
    Assignee: Max-Planck-Gesellschaft zur Foerderung der Wissenschaften E.V.
    Inventors: Peter Seeberger, Hansjoerg Gruetzmacher, Klaus Tauer, Judith Braeuer, Paola Laurino
  • Ultra fast process for the preparation of polymer nanoparticles
    Patent number: 8921442
    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?1.
