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.
