English
Chemical Dehydrochlorination of Poly(vinyl chloride) in the Presence of Poly(vinyl butyral)
Abstract:
PVC has been dehydrochlorinated by alkali alkoxide in the presence of poly(vinyl butyral)(PVB). Effects of time, reagents and PVB on the reaction have been studied. The solution and product was analyzed by UV-Vis spectrophotometry and FTIR. A highly dehydrochlorinated PVC and stable product with long trans-(CH)x chain sequences has been found.
