  • 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.

  • Patent number: 8029897
    Abstract: The invention relates to nanometric or mesoscopic dissymmetric particles, and to a method for preparing the same. The particles have an inorganic part A and a spherical organic part B bound by physicochemical or covalent interactions. Material A is a metal oxide, a metal or a metal chalcogenide. Material B is a polymer consisting of recurrent units derived from a vinyl compound. The particles are obtained by modifying the surface of material A particles with a coupling agent C having a function FC which exhibits affinity for the polymer, and contacting the modified inorganic particles with the precursor(s) of the polymer B, in the presence of a free radical initiator and of a surfactant in solution in a solvent.

  • Publication number: 20080038176
    Abstract: The invention relates to unsymmetrical nanoscale or mesoscopic particles, and to a method for preparing the same. Said particles are characterized by a surface F1 and the zone Z2 carries groups F2 different from the groups F1, the zone Z1 being free of groups F2 and the zone Z2 being free of groups F1. The method of preparation comprises the following steps: 1) the zone Z2 of the surface of the initial particles is masked by fixing a polymer nodule thereto; 2) the masked particles obtained at the end of step 1) are treated in order to modify the nonmasked surface zone Z1 thereof; 3) the polymer nodule is removed after modifying the zone Z1; 4) optionally, the surface of the zone Z2 of the particles is modified following the demasking process.

  • Patent number: 5310534
    Abstract: A process is provided for dealuminization of zeolites having large pores, the diameter of the aperture of the pores being greater than or equal to about 0.7 nm and the silica/alumina ratio greater than or equal to about 6. The process comprises acid leaching of the raw zeolite containing the structuring agent.The dealuminized zeolites obtained are useful as catalysts for the transformation of hydrocarbons and as selective organophilic adsorbents.
