International audienceThe radical copolymn. of three polymerizable surfactants with styrene was investigated by NMR spectroscopy to assess their compns. The reactivity ratios of these monomers were calcd. according to the methods of Fineman-Ross and Kelen-Tuedos. Consequently, Q and e values were deduced by the Alfrey and Price method. The results indicated the pos. effect of the fluorine chain on the reactivity of monomers bearing a long spacer between the ammonium head and the acrylic function. These monomers exhibit high e values which are in favor of an intramol. conformation of the surfactant where the ester carbonyl function of the polymerizable group interacts with the onium nitrogen atom via a compact six-sided structure
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.
