| 20110034588 | METHOD OF PREPARING A TRANSPARENT POLUMER MATERIAL COMPRISING A THERMOPLASTIC POLYCARBONATE AND MINDERAL NANOPARTICLES - A method of preparing a transparent polymer material includes mixing mineral nanoparticles selected from nanoparticles of alkaline-earth metal carbonates, alkaline-earth metal sulfates, metallic oxides, oxides of metalloids, and siloxanes, and a composition A including at least one thermoplastic polymer in the molten state selected from polycarbonate (PC), polystyrene (PS) and polymethyl methacrylate (PMMA) in order to obtain a master-batch, the mixture of step i) including at least 25% and at most 75% by weight of the mineral nanoparticles. The master-batch obtained in step i) is mixed with a composition B of a thermoplastic polycarbonate matrix (PCm) in the molten state, to obtain a transparent polymer material including at most 10% by weight of the mineral nanoparticles, preferably at most 5% by weight of the mineral nanoparticles. | 02-10-2011 |
