Furthermore, the present invention relates to the use of the polycarbonate compositions according to the invention for the production of battery housings,
- EP 0 363 608 describes polymer blends of aromatic polycarbonate, styrenic copolymer or graft copolymer and oligomeric phosphates as flame retardant additives.
- the mechanical property level at low application temperatures, in particular the Bindenahtfestmaschine and the flow behavior is not sufficient.
- EP 0 704 488 describes molding compositions of aromatic polycarbonate, styrene-containing copolymers and graft polymers with a specific graft base in specific proportions. If desired, these molding compositions can be rendered flame-resistant with phosphorus compounds. These molding compounds have a very good notched impact strength, but flow behavior, flame retardance and chemical resistance are not sufficient for certain applications.
- EP 747 424 describes thermoplastic resins containing phosphate compounds having a molecular weight of 500 to 2000 and phosphate compounds having a molecular weight of 2300 to 11000 as a flame retardant, listing a variety of thermoplastic resins. Due to the high molecular weights of the phosphorus compounds, the flow behavior of the molding compositions is significantly impaired.

These molding compositions have a high heat resistance and excellent mechanical properties (notched impact strength and Bindenahtfestmaschine), however, the flow behavior and flame retardancy are not sufficient, especially in the case of moldings with thin walls.
- EP 1 165 680 describes flame-retardant PC / ABS molding compositions having good mechanical properties (tensile strength, weld line strength) containing oligomeric phosphates with a defined chain length.
