Gel permeation chromatography in the study of the molecular weight distribution vinyl chloride–vinyl acetate copolymer. III. Influence of the incompatibility of polymers and some problems of interpretation of experimental data
Abstract:SynopsisThe influence of incompatibility in the ternary systems gel-polymer-solvent and polymer-polymer-solvent on the results of gel permeation chromatography of the copolymer vinyl chloride-vinyl acetate was investigated. The measurements were performed on styrene-divinylbenzene gels and on porous silica gels. Detection in GPC was made using a differential refractometer together with a UV detector, which permitted evaluation of the extent of interactions of the polymer components in the mixture. Some aspects… 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.
