"Method For Preparing A Transparent Polymer Material Including Mineral Nanoparticles With A Shape Factor Strictly Higher Than 1.0"
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. Translation of the title and the abstract as they were when originally filed by the Applicant. No account has been taken of any changes that might have been made subsequently by the PCT Authorities acting ex officio, e.g. under PCT Rules 37.2, 38.2, and/or 48.3.
