Abstract: The invention relates to a polycarbonate composition and copolycarbonate composition ((co)polycarbonates) with improved optical properties of the mouldings produced therefrom.

Abstract: The invention relates to polymer compositions for the production of mouldings, in particular spectacles and eye-protection equipment, which comply with the provisions of EN 169 (welder protection standard) and EN 1836/2005 (signal light detection). The compositions and mouldings are in particular processable at temperatures above 265° C., recyclable and have a notched impact strength of at least 65 kJ/cm2, and they comply with the required optical standards mentioned above.

Abstract: The present invention relates to polycarbonate compositions and copolycarbonate compositions having improved optical properties, and to their production and their use for the production of shaped parts, and to shaped parts which can thereby be obtained, the compositions containing a polycarbonate or copolycarbonate which comprises bisphenol-A and at least one pair of a phosphorus compound having the oxidation number +3 and a phosphorus compound having the oxidation number +5, and the phosphorus compound having the oxidation state +5 in a pair respectively corresponding to the oxidized form of the phosphorus compound having the oxidation state +3 and the amount of more highly oxidized compound contained being less than that of the compound with the lower oxidation number.

Abstract: The present invention relates to a heat-absorbing polymer composition containing a transparent thermoplastic synthetic substance, an inorganic infrared absorber with stabilizer and also to the production and use of the polymer compositions according to the invention and to the products produced therefrom. In particular, the present invention relates to the stabilization of inorganic IR absorbers from the group of the tungsten compounds and also to the use of the polymer composition according to the invention containing these stabilized inorganic IR absorbers for the purpose of producing windowpanes for use in buildings, motor vehicles, rail vehicles or aircraft.
