  • Synthesis of surfactant-free poly (vinylidene fluoride) latexes via raft emulsion polymerization
    Patent number: 11326008
    Abstract: The present invention relates to a process for producing a stable fluorinated latex by emulsion polymerization in the absence of fluorinated surfactant, stabilized by an amphiphilic block copolymer formed in situ. The invention also concerns the aqueous dispersion comprising the fluorinated polymer chains and the amphiphilic block copolymers, obtained by this process.
    Type: Grant

  • Process for the preparation of a vinylidene chloride polymer/clay composite, films obtained therefrom, and use thereof
    Patent number: 10982110
    Abstract: The present invention relates to a process for preparing a vinylidene chloride polymer composite comprising a vinylidene chloride polymer and clay materials. The process comprises polymerising vinylidene chloride and clay materials and the resulting vinylidene chloride polymer particle is surrounded by a plurality of clay platelets. The clay materials according to the present invention function as a solid stabilizer in the process for preparing a vinylidene chloride polymer composite of the present invention. The present invention further relates to the vinylidene chloride polymer composite obtainable from the process, to use of the vinylidene chloride polymer composite for the preparation of films, and to films prepared therefrom.

  • Emulsion polymerization in the presence of a stable free radical
    Patent number: 6353065
    Abstract: A process for the emulsion polymerization in the presence of a stable free radical of at least one monomer which can be polymerized by the radical route, which emulsion comprises a liquid aqueous phase and a liquid organic phase, the aqueous phase comprising at least 50% by weight of water and the liquid organic phase comprising more than 50% by weight of monomer(s) to be polymerized. The invention results, by a rapid controlled polymerization process, in a latex of polymer particles, it being possible for the polymer to comprise acrylate and/or methacrylate blocks.
