ABSTRACT:
The present invention relates to a process for the preparation of a composite polymeric material containing nanometric inorganic inclusions comprising the steps of: mixing a polymer with a thermolytic precursor to provide a homogeneous dispersion of said at least one precursor and of said at least one polymer; subjecting said homogeneous dispersion to heating to provide a molten polymer and thermolytic fission of the precursor, generating the inclusions dispersed in the molten polymer.
