| Abstract: | For the Poly(vinyl chloride)(PVC)/Poly(ethylene glycol)(PEG)/Potassium hydroxide(KOH)reaction system,effects of solvent type,PVC concentration and reaction time on dechlorination of PVC have been investigated.Results proved that the addition of solvents could effectively enhance the dechlorination of PVC for the PVC/PEG/KOH system.Moreover,the properties of solvents as well as the PVC concentration greatly influence the dechlorination behaviors of PVC.When the PVC concentration is less than 1.6 wt%,PVC owns... |
