The thermal decomposition of dicumyl peroxide under the flow nitrogen atmosphere was studied by DSC-TG technique.The non-isothermal kinetics parameters were analyzed by means of the Kissinger and Flynn-Wall-Ozawa methods,and the thermal decomposition mechanism of dicumyl peroxide was also studied with the Satava-Sestak method.The results showed that there was little difference between kinetic parameters calculated by DSC plot and DTG plot,the apparent activation energy and pre-exponential factor were 120.83 kJ·mol-1 and 9.12×1011s-1,respectively.The thermal decomposition mechanism of dicumyl peroxide in nitrogen was controlled by interface reaction R3.
