Zusammenfassung:	Thermoplastic moulding materials (I), containing (A) 25-97 pts. wt. polyalkylene terephthalate (PAT), (B) 3-20 pts. wt. di-sodium tetrabromophthalate (DSTBP), (C) 0-10 pts. wt. antimony trioxide or pentoxide and (D) 0-45 pts. wt. reinforcing material, in which the sum of (A+B+C+D) = 100 pts. wt., up to 25 pts. wt. PAT may be replaced by aromatic polycarbonate and/or a graft copolymer, and 1-10 pts. wt. (based on 100 pts. wt. total) polyolefin may also be added. Also claimed are moulded products made from (I). Preferably suitable graft copolymers are derived from at least 2 comonomers selected from chloroprene, isoprene, butadiene, styrene, acrylonitrile, ethylene, propylene, vinyl acetate and (1-18C alkyl) (meth)acrylates. Preferred graft copolymers are based on polybutadienes, butadiene/styrene copolymers, poly(meth)acrylate esters or copolymers of styrene or alkylstyrene and conjugated dienes, grafted with styrene and/or acrylonitrile and/or alkyl (meth)acrylate. Materials (I) may contain conventional additives, especially lubricants and mould release agents, processing aids, dyes and pigments.
