Zusammenfassung:PROCESS FOR THE PREPARATION OF A MOULDING MATERIAL OR A MOULDING COMPRISING A THERMOPLASTIC, CONTAINING NANOSCALE, INORGANIC PARTICLES, THE THERMOPLASTIC BEING MIXED IN THE MOLTEN STATE WITH THE NANOSCALE INORGANIC PARTICLES AND A SOLUBILIZER IN AN EXTRUDER HAVING SCREW TRANSPORT, PRESSURES AND TEMPERATURES AT WHICH THE PLASTIC IS PRESENT AS A MELT AND THE SOLUBILIZER IS PRESENT IN THE SUPERCRITICAL STATE BEING SET, CHARACTERIZED IN THAT THE MIXTURE IS TRANSPORTED AT THE EXIT OF THE EXTRUDER THROUGH A PASSAGE OF LESS THAN 20 ?M INTO A FLASH ZONE AND THE MELT IS DISCHARGED WITH THE INCORPORATED, NANOSCALE, INORGANIC PARTICLES, COMMINUTED AFTER COOLING TO GIVE A MOULDING MATERIAL OR TRANSFERRED INTO A SHAPING PROCESSING TOOL AND SHAPED TO GIVE A MOULDING. THE INVENTION FURTHERMORE RELATES TO THE MOULDING MATERIAL AND MOULDINGS OBTAINABLE BY THE PROCESS ACCORDING TO THE INVENTION AND TO THE USES THEREOF.
