| 摘要 |
The present invention relates to a process for producing thermoformed moulded articles, wherein: (i) a composition containing the components A) 60-85 parts by weight of a branched aromatic polycarbonate and/or branched aromatic polyester carbonate, B) 1-25 parts by weight of a graft polymer including one or more graft bases selected from the group comprising the silicon rubbers and silicone-acrylate rubbers, C) 10-15 parts by weight of talc, D) 0.4-20 parts by weight of phosphorus-containing flameproofing agents, E) 0.5-20 parts by weight of one or more inorganic boron compounds, and F) 0-3 parts by weight anti-driping agents is melted and mixed, wherein all part by weight for (A) to (F) are normalised such that the sum of the parts by weight is 100, (ii) the resulting melt is cooled and granulated, (iii) the granulate is melted and extruded into sheets and (iv) the sheets are shaped into a three-dimensional object, that satisfy enhanced fire-protection requirements, and to the moulded articles that can be obtained by this process.
