Abstract:In order to assign all -CH,CI resonances observed by ' H NMR in poly(viny1 chloride), (PVC), a preliminary study of the diastereoisomers of molecular models for the groups CH2Cl-CHCI- [11] and ClCH,-CH< [IV] is used, in conjunction with spin echo experiments. The complex region [3,5 -4,O ppm] which corresponds to saturated -CH,CI chloromethyl protons is completely assigned. A separate evaluation of -CHCI-CH,CI[II], -CH,-CH,CI[III] and >CH-CH,CI [IV] is proposed and tested on raw PVC samples. The main interest… 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.
