The role of FeSO4 in the obtaining of polyvinylpirrolidone copolymers

The proceeding of 2-hydroxyethylmethacrylate grafted polymerization on polyvinylpirrolidone has been examined in the presence of ferrum(II) sulfate. It was observed the formation of crosslinked copolymer capable to be used as a matrix for metal chemical reduction and for metal hydrogel composites obtaining. The effect of Fe structure and concentration on the structural parameters of the polymeric network, copolymers composition, efficiency and degree of grafting has been determined. The interaction between the structure of the synthesized copolymers and their thermal and physicomechanical properties has been established. Кеуwords: copolymerization, copolymer, 2-hydroxyethylmethacrylate, polyvinylpirrolidone, hydrogel, structure.
