Thermal degradation kinetics of PE by the Kissinger equation

Thermal degradation kinetic parameters of two forms of polyethylene were investigated by using thermogravimetric analysis and the Kissinger equation. Under the oxygen presence, polyethylene was decomposed rapidly at lower temperature by additional oxidation reaction. The thermal decomposition activation energy of low density polyethylene and cross-linked polyethylene were 146.8 kJ mol(-1) and 170.4 kJ mol(-1), respectively. (C) 1998 Elsevier Science S.A.
