Sequence distributions of several radical copolymers of vinylidene chloride were examined by NMR spectroscopy, including methyl methacrylate, benzyl methacrylate, methacryloyl chloride, methyl acrylate, a-methylstyrene, styrene, and vinyl acetate as comonomers. Except for the a-methylstyrene and styrene systems, some of the diad, triad, and tetrad sequences were observed in the CH, and a C H , resonances and are discussed in the light of the usual copolymerization theory.
ZUSAMMENFASSUNG:Die Sequenzverteilung einiger radikalisch gehildeter Copolymerer des Vinylidenchlorids wurde durch NMR-Spektralanalyse untersucht, wobei als Comonomere Methylmethacrylat, Benzylmethacrylat, Methacrylsaurechlorid, Methacrylat, a-Methylstyrol, Styrol und Vinylacetat verwendet wurden. Ausgenommen bei den a-Methylstyrol und Styrol enthaltenden Systemen, wurden an Hand der CH,und aCH3-Resonanzstellen einige Diaden, Triaden und Tetraden heobachtet und im Rahmen der iiblichen Copolymerisationstheorie erortert.
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.
