a Heat mappings of C-Cl bond regions identified by FTIR. b TG, and DTG curves of PVC and vitrimer. c Correlations between the C/Cl ratio and residence time, three measurements were conducted for each data point with the error bars corresponding to the standard deviation. d First-order dechlorination kinetic fitting lines. e XPS analysis of dechlorination process i, C 1 s, ii, Cl 2p, and iii, S 2p spectrum, the color-filled portion indicates the peak integration area. f TGA-FTIR-GC/MS of decomposition products. g Pre-separation of plasticizer from waste PVC gloves. h Comparison of dechlorination efficiency using PVC gloves versus pristine PVC powder as chlorination substrates.
