英文摘要	The thermal decomposition kinetics of polybutylene terephthalate (PBT) and flame-retardant PBT (FR-PBT) were investigated by thermogravimetric analysis at various heating rates. The kinetic parameters were determined by using Kissinger, Flynn-Wall-Ozawa and Friedman methods. The y(α) and z(α) master plots were used to identify the thermal decomposition model. The results show that the rate of residual carbon of FR-PBT is higher than that of PBT and the maximum mass loss rate of FR-PBT is lower than that of PBT. The values of activation energy of PBT (208.71 kJ/mol) and FR-PBT (244.78 kJ/mol) calculated by Kissinger method were higher than those of PBT (195.54 kJ/mol) and FR-PBT (196.00 kJ/mol) calculated by Flynn-Wall-Ozawa method and those of PBT (199.10 kJ/mol) and FR-PBT (206.03 kJ/mol) calculated by Friedman methods. There is a common phenomenon that the values of activation energy of FR-PBT are higher than that of PBT in different methods. The thermal decomposition reaction models of the PBT and FR-PBT can be described by Avarami-Erofeyev model (A1). © 2019 Trans Tech Publications Ltd, Switzerland.
