Abstract: The invention relates to a composition for production of a thermoplastic moulding compound, wherein the composition comprises or consists of the following constituents: A) 50-90% by weight of aromatic polycarbonate or polyestercarbonate having a relative solution viscosity of at least 1.285, measured in CH2Cl2 as solvent at 25° C. and a concentration of 0.5 g/100 ml, B) 1-10% by weight of rubber-modified graft polymer, C) 2.5-10% by weight of boron nitride, D) 4-20% by weight of talc, E) 2-20% by weight of phosphorus-containing flame retardant, F) 0-20% by weight of further additives, and to a process for producing the thermoplastic moulding compound, to the moulding compound itself, to the use of the moulding compound for production of mouldings and to the mouldings themselves.

Abstract: The present invention relates to a polymer composition containing polycarbonate with a weight-average molecular weight Mw of from 24,000 to 33,000 and 5.0 wt. % to 20.0 wt. % (based on the total amount of the composition) of glass hollow spheres with an alkalinity of less than 1.0 meq/g. The present invention furthermore provides coextruded sheets in which the coextruded layer contains this polymer composition, and shaped articles produced therefrom, in particular containers and pieces of luggage, very particularly suitcases. Sheets which are obtainable with the polymer composition according to the invention have a high mechanical stability, a high scratch resistance, pleasant haptic properties and an excellent homogeneous external visual impression. The present invention furthermore relates to a process for the preparation of these polymer compositions and a process for production of the sheets according to the invention.

Abstract: A multilayer sheet suitable for use as a diffuser in flat screens is disclosed. The sheet includes at least one base layer (B) and at least one outer layer (A) wherein (B) comprise a transparent thermoplastics material and transparent polymeric particles, with the proviso that the refractive index of the material and particles differ one from the other, and wherein said (A) comprise a transparent polycarbonate and a bismalonate UV absorber.

Abstract: A solid sheet comprising 80 to 99.99 wt. % of a transparent polycarbonate having weight average molecular weight of 15,000 to 21,000 g/mol, specifically excluding 18,000 g/mol, and 0.01 to 20 wt. % of transparent polymeric particles having an optical density which differs from that of the polycarbonate is disclosed. The sheet is particularly suitable as a diffuser in flat screens.

Abstract: A process for treatment of the plastic profiles is disclosed. The process entails extruding and calibrating a plastic profile and then passing the profile through a bath containing at least one additive.
