Use of a selected combination of an ionic hydrocarbon copolymer and antimony trioxide in the presence of a halogenated flame retardant has been found to increase flame-retardancy without lowering thermal stability of a reinforced or filled polyethylene terephthalate molding blend which contains a sodium or potassium salt of an ionic hydrocarbon copolymer and a low molecular weight compound that is an ester, ketone, sulfone, sulfoxide, nitrile or amide. |
