Abstract
The thermal degradation of polyethylene (PE) was carried out in the absence and presence of
catalystes X-Zeolite and Silica-Alumina at different temperatures. The optimum PE/Catalysis
ratio was 0.25:0.05 g/g, which produced highest degradation value. PE and PE/Catalysis were
characterized by thermogravimetric analysis. The thermal degradation properties of polymer
have been studied by Infrared spectroscopy–FT-IR. Experimental data indicated that the
presence of catalysis greatly increased the rate of degradation of PE. The activation energy of
degradation for pure polyethylene and polyethylene in presence catalysises was calculated by
Arrhenius equation and Ozawa method. Activation energy follows the order PE < PE/Silica-
Alumina < PE/X-Zeolite.
