Poly(trimethylene terephthalate) compositions, and articles made therefrom, having improved flame retardancy are provided. The compositions can be used to make carpets that are suitable for installation where flame retardancy is desired. The compositions contain particulate flame retardants having an average particle size of less than about 10 micrometers. L'invention concerne des compositions de poly(téréphtalate de triméthylène) et des articles faits à partir de celles-ci, ayant un retard de flamme amélioré. Les compositions peuvent être utilisées pour fabriquer des tapis qui sont appropriés pour une installation où un retard de flamme est souhaité. Les compositions contiennent des retardateurs de flamme particulaires ayant une dimension moyenne de particule de moins d'environ 10 micromètres.
