The Investigation of Thermal Decomposition Kinetics for PNIMMO by TG-MS

Hai Chang

Abstract

The whole processes of the PNIMMO thermal decomposition was investigated by using simultaneous DSC-TG-MS.The kinetic parameters of PNIMMO decomposition was obtained from equation Kissinger and equation Ozawa.Equation Kissinge:E= 179.1 kJ.mol-1、lnA= 45.85s-1,equation Ozawa:E= 177.4kJ.mol-1、lnA= 39.19s-1。The mechanism functions of PNIMMO decomposition from equation Coats-Redfern was first order reaction.The PNIMMO decomposition gaseous products were studied,the mechanism of PNIMMO decomposition was analyzed.
