Abstract
A flame-retarded polyester molding composition having improved physical properties comprising PA0 (a) a polyester containing repeating units from terephthalic acid and 1,4-cyclohexane-dimethanol, and PA0 (b) a flame-retardant system comprising about 5-20% by weight of the composition of an aromatic organic compound having at least one aromatic ring in which the compound has sufficient halogen bonded directly to the aromatic ring to provide flame-retardant properties and about 2-8% by weight of the total composition of powdered antimony metal having a particle size of less than about 500 microns.
