Comparison with studies by other authors.

Authors	Sample	Temperature (°C)	Main Results
Wang et al. [24]	PVC-CuO	190	CuO was chlorinated by PVC at 190 °C.
Ji et al. [18]	PVC-CuO	280	(i) CuO absorbed the HCl produced by pyrolysis; (ii) the production of benzene was significantly reduced.
Meng et al. [16]	PVC-CuO	310	The proportion of HCl decreased from 94.7% (for PVC) to 80.9%.
Blazsό and Jakab [33]	PVC-CuO	550	(i) Two-thirds of the HCl emissions were reduced; (ii) benzene formation was hindered.
Grimes et al. [21]	PVC-CuO	300, 600	(i) Chloroaromatics were the main chlorinated organic compounds (COCs); (ii) chlorine emissions were reduced by 20%; (iii) benzene emissions were reduced by more than 90%.
Wang et al. (this work)	EPET-PVC-CuO	440, 640	(i) Chloroaromatics were the main COCs; (ii) COCs were reduced by 75%; (iii) HCl emissions were reduced by 71%.
