Flame-resistant polyester moulding compounds comprising (A) 70-95% by weight of a specific polyester mixture made up of polyethylene terephthalate, polybutylene terephthalate copolyester with 3-30 mol % of an aliphatic dicarboxylic acid containing up to 36 C atoms, and, if desired, polybutylene terephthalate, and (B) 30-5% by weight of a flame-retardant additive made up of a bromine-containing organic compound and an antimony compound selected from the group comprising Sb2O5, NaSbO3 and Sb2O3, with a mean particle size of not less than 2 mu m, are particularly suitable for the production of partially crystalline mouldings by means of injection moulding. The mouldings are distinguished by a light self-colour with comparatively good thermal, mechanical and electrical properties.
