Abstract (en)
[origin: WO2009074554A1] The present invention relates to a method for preparing a transparent polymer material comprising the following steps: i. obtaining composite nanoparticles comprising mineral nanoparticles at least partially coated with at least one monomer and/or with at least one polymer capable of promoting the physicochemical interactions at the interface between the mineral nanoparticles and a thermoplastic polycarbonate matrix, wherein said mineral nanoparticles are surface-modified with said monomer and/or said polymer, either directly by grafting or indirectly by adsorption of the monomer and/or of the polymer at the surface of said mineral nanoparticles, or by means of a coupling agent chosen from a chlorosilane or an organosilane comprising a functional group capable of reacting via a radical route, and ii. mixing the composite nanoparticles, obtained in step i, with the thermoplastic polycarbonate matrix in the molten state, so as to obtain said transparent polymer material.
