Polyacrylonitrile, poly(styrene-acrylonitrile) and poly(acrylonitrile-butadiene-styrene) complexes with transition metal salts have been synthesized. The synthesis were attempted by carrying out free radical polymerization reactions in aqueous transition metal salt solutions (ZnCl 2 , CuCl 2 , CoCl 2 , CoSO 4 , NiSO 4 , CuSO 4 ) and by addition of the transition metal salts to the reaction mixture in the final stage of the polymerization. It is shown experimentally and theoretically that the first method is successful only when zinc chloride is used, while the cobalt, nickel, copper complexes are formed through the addition of the salts to the ready polymers. Reactions that take place during studied complexations were investigated by means of ab initio quantum chemistry calculations, thermodynamic parameters for these reactions were determined.
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.
