The effect of ZnO in the decomposition of poly(vinyl chloride) (PVC) and polystyrene (PS) mixtures in air atmosphere has been studied by thermogravimetry (TG) and gas chromatograph-mass spectrometry (GC-MS) under various mixing ratios and reaction temperatures. From this work, it can be seen that the yields of a liquid product were increased with the increase of PS in mixtures, whereas those of gaseous products were decreased. And the yields of a gaseous product and HCl were decreased with the increase of ZnO in mixtures. It was also found that HCl was rarely produced at ZnO/Mixture = 0.5 by the effect of ZnO in dehydrochlorination of PVC.

공기분위기에서 PVC와 PS의 혼합 분해시 ZnO의 영향에 관한 연구를 혼합비율 및 반응온도를 변화시키며 TG와 GC-MS를 이용하여 수행하였다. 본 연구로부터 혼합물에 있어서 PS의 양이 증가할수록 액상 생성물은 증가하였 으며 기상 생성물은 감소함을 알 수 있었다. 또한 혼합물에 있어서 ZnO의 첨가량이증가할수록 가스 생성물과 염화수소의 발생량은 감소하였으며 ZnO/Mixture = 0.5인 경우 ZnO의 영향에 의하여 염화수소가 거의 생성되지 않음을 확인할 수 있었다.
