The thermal decomposition kinetics of the aluminum diethylphosphinate ( DEPA) flame re-tardant was studied by TG-DTG techniques .The kinetic parameters , including the activation energy and fre-quency factor of the decomposition process for the compound were calculated through the Kissinger -Akahira-Sunose (KAS) and Flynn-Wall-Ozawa ( FWO) method and the thermal decomposition mechanism was also studied with the ?atava-?esták method.The results show that the activation energy was 260.2 kJ/mol and with the KAS method and 259 .4 kJ/molwith the FWO method respectively .The thermal decomposition mechanism belongs to phase boundary reaction and the kinetic equation of the novel flame retardant can be expressed as g(α) =1 -(1 -α) 1/3 .
