Flame retarded thermoplastic compositions which comprise in intimate admixture: (a) a polyethylene terephthalate, (b) a copolymer of a vinyl aromatic compound and an alpha,beta-unsaturated cyclic anhydride, said copolymer being a rubber-modified graft copolymer or a rubber-free copolymer, (c) a bis-imide flame retardant having at least 8 halogen atoms in the molecule bonded to carbon atoms of aromatic ring systems, (d) optionally, an inorganic synergist for said flame retardant. The compositions preferably contain an impact modifier as well.
