Abstract:C HEMICAL modification of poly(vinyl chloride), PVC, was performed via its substitution reaction with 6-amino-2-thioxo-tetrahydropyrimidin-4-one (1) and three of its derivatives (1A-C). The chemical structures of the modified PVC samples have been confirmed via FTIR and 1 HNMR spectroscopic analyses. Photostability of the modified PVC were investigated by following the rates of dehydrochlorination of the 6-aminopyrimidine derivatives modified PVC samples conductometrically in comparison with both blank PVC and… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
