Abstract
A flame retardant polyester resin composition including polyester containing phosphorus, preferably about 0.05 to about 1.5 weight % based on the total weight of the composition, of at least one platy inorganic material. The composition provides excellent flame retardant and anti-dripping properties, especially to oriented polyester film formed from the composition. The polyester may include additional phosphorus that is covalently bonded to the polymer, or physically incorporated into the polyester such as by means of masterbatch.
