- METHOD FOR PREPARING A TRANSPARENT POLYMER MATERIAL COMPRISING A THERMOPLASTIC POLYCARBONATE AND SURFACE-MODIFIED MINERAL NANOPARTICLES

摘要

The present invention provides a method for producing a transparent polymer material comprising the steps of: i) obtaining a composite nano-particles comprising mineral nanoparticles, and a thermoplastic polycarbonate, at least in part of mineral nanoparticles coated with at contact points between the matrix of one or more monomers and / or one or more polymers suitable for promoting physical and chemical interaction comprising, The mineral nanoparticles, directly by the monomers and / or adsorption of the polymer on the surface of the mineral nanoparticles, or directly by the graft; or, via a coupling agent selected from the organic silane or chlorosilane containing a functional group capable of reacting by a radical route, The monomer and / or surface by the polymer-modified in step one; And ii) wherein i) the melting of the composite nanoparticles obtained in step Status thermoplastic polycarbonate matrix and mixed to obtain a transparent polymeric material.
