N2 - Thermal degradation of Ethylene Propylene Diene Rubber (EPDM) and PVC have been investigated and compared by means of TG/DTA in air or N 2 atmosphere with the heating rate of 10K/min and gas chromatography-mass spectrometry (GC-MS). The occurrence of primary and second thermal degradation stages of EPDM in air have been recognized, while in N 2 it was only one stage. The total weight loss ratio in air and N 2 was 61.3%, 60.7%, respectively. Three degradation stages of PVC occur in both air and N 2 and the total weight loss ratio was 72.5%, 72.6%, respectively. The thermal degradation of EPDM are all endothermic reaction, while of PVC are mainly exothermic reaction. Combustion products heated by laser in the same experimental conditions have been analyzed by GC-MS, the amount of toxic substances differ greatly, the amount of dimethylmethane of PVC are 2.55 times more than EPDM, dimethylbenzene and styrene of PVC are 6.2 and 5.5 times more than EPDM, toluene and benzene of PVC differ greatest with EPDM, are 24.2 and 35.7 times, respectively. EPDM can significantly reduce toxic products generation compared with PVC.
