FIELD: chemistry.

SUBSTANCE: invention relates to a thermoplastic moulding composition which is flame retardant and impact resistant. The thermoplastic moulding composition for making moulded articles contains aromatic polyester carbonate, polyalkylene terephthalate, graft copolymer having a nucleus-shell morphology, having a graft shell which contains polymerised alkyl(meth)acrylate, and a nucleus made from composite rubber which contains interpenetrating and inseparable polyorganosiloxane and poly(meth)alkyl acrylate components in form of particles having size from 0.05 to 5 mcm and glass transition temperature lower than 0°C, and where the weight ratio polyorganosiloxane/poly(meth)alkyl acrylate/hard shell equals 70-90/5-15/5-15, and a phosphorus-containing compound (IVa), where R¹, R², R³ and R⁴ denote phenyl, R⁵ denotes hydrogen, n equals 1, q ranges from 1 to 2, Y denotes C(CH₃)₂ and fluorinated polyolefin.

EFFECT: high resistance to inflammation and impact strength.
