Abstract:
The present invention provides a method of preparing a transparent polymer material, the method comprising steps i) and ii) in any order, the steps consisting in: i) mixing: mineral nanoparticles having a form factor strictly greater than 1.0; and a polymer matrix comprising a quantity of at least 80% by weight of a polycarbonate (PC) first thermoplastic polymer and of a second transparent thermoplastic polymer other than the first thermoplastic polymer, in order to obtain a mixture; and ii) heating the polymer matrix to the molten state, on its own or in the mixture; to obtain the transparent, polymer material, the mixture of step i) comprising a quantity of mineral nanoparticles having a form factor strictly greater than 1.0 that is strictly less than 5% by weight.
