The limited oxygen index and cone calorimetry tests indicated that the introduction of 5 wt % BDPP significantly improved the flame‐retardant properties of PTT through a synergistic char‐formation mechanism in the condensed phase and a flame‐inhibition mechanism in the gas phase. The PTT–BDPP blend also demonstrated an evident reduction in the melt viscosity but a superior melt stability in comparison to the neat PTT. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
