ABSTRACT:Copolymerization of ethylene with vinyl acetate was carried out at room temperature by the ternary catalyst system consisting of equimolar amounts of AlEts, ZnCh and CCk By solvent fractionation and thin layer chromatography analysis, the copolymerization product was found to consist of two different copolymer fractions. One was the 1 : 1 alternating copolymer and the other was identified with the copolymer produced by the usual free radical initiator under the same reaction conditions. Two different catalyst sites were assumed, i.e.,
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.
