Abstract
The present invention relates to the combination of halogen-free flame retardant additives in a copolyester to improve the flame retardant properties of the copolyester composition while retaining impact properties, methods of making the copolyester composition and articles made from the copolyester composition. More specifically, the present invention relates to the use of a nitrogen containing flame retardant and a metal phosphorous-containing compound in copolyester compositions to improve the flame retardant properties while retaining impact properties, methods of making said copolyester compositions and articles therefrom.
