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.

Structural Conformation of Polytetrafluoroethylene Composite Matrix

Enhancement of physical and mechanical properties and structuring activity of polytetrafluoroethylene as matrix of composites by means of mechanical activation is shown. Operating modes of mechanical activation equipment are defined, in which the service properties of PTFE are maximized. The effect of mechanical activation technology on restructuring and change of morphology and supramolecular structure of PTFE is detected for the first time.
