英文摘要：

The non-isothermal thermal decomposition process of bisphenol fluorene diamine benzoxazine resin was studied with TG-DTG technology.The corresponding kinetic parameters such as activation energy（E）and pre-exponential factor（A）were obtained according to the Kissinger and Ozawa methods. A dynamic function and the mechanism of thermal decomposition reaction of resin were proposed by the model method and the corresponding energies were further verified applying the model-free method.The results show that the activation energy,the pre-exponential factor and the order of the reaction（ n） are about E=260.55 kJ/mol,lgA= 16.98 and n=1/5,respectively.The differential mechanism function is f（α）=n（1-α）×[-ln（1-α）]1^-1n and the integral function is g（α）=[-ln（1-α）]^1/n. The thermal decomposition reaction mechanism follows the random nucleation and subsequent growth and the corresponding reaction function is：dα/dT=（9.55×10^16/β）exp（-260.55×10^3/RT）×1/5（1-α）×[-ln（1-α）]^-4.
