Water-Soluble Vanadium Metal–Polymer Nanocomposites

Methods were developed for the synthesis of water-soluble metal–polymer nanocomposites of vanadium citrate complex with vinylphosphonic acid copolymers with acrylamide or 2-dimethylaminoethyl methacrylate. It was shown that the vanadium complex binds to the copolymer in an acid medium, while in a ne...

Zusammenfassung:	Methods were developed for the synthesis of water-soluble metal–polymer nanocomposites of vanadium citrate complex with vinylphosphonic acid copolymers with acrylamide or 2-dimethylaminoethyl methacrylate. It was shown that the vanadium complex binds to the copolymer in an acid medium, while in a neutral medium, the nanocomposite dissociates to release the free complex. With a molar excess of the vanadium complex, intramolecular cross-linkings occurs, which leads to compaction of macromolecules.
