Abstract

Flame resistant thermoplastic moulding compositions consisting of PA0 (a) from 5 to 85 parts, by weight, of an aromatic polycarbonate, PA0 (b) from 15 to 95 parts, by weight, of a SAN-graft polymer, PA0 (c) from 0 to 50 parts, by weight, of a thermoplastic polymer, PA0 (d) optionally from 3 to 15 parts, by weight, (per 100 parts by weight of (a)+(b)+(c) of an organic, low molecular weight, oligomeric or polymeric halogen compound, PA0 (e) from 0.05 to 5 parts, by weight, (per 100 parts by weight of (a)+(b)+(c)) of antimony trioxide, antimony carbonate, bismuth trioxide or bismuth carbonate, and PA0 (f) from 0.05 to 0.5 parts, by weight, based on 100 parts, by weight, of the sum of (a)-(f), of finely-divided tetrafluoroethylene polumer having a fluorine content of from 65 to 76%, by weight, and a process for the production thereof.
