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 Fen+ structure and concentration on the structural parameters of the polymeric network, copolymers composition, efficiency and degree of grafting has been determined.
