Abstract: 
The influence of a constant magnetic field on the polymerization kinetics and structural parameters of a hydrogel network on the basis of 2-hydroxyethylmethacrylate and polyvinylpyrrolidone compositions has been investigated. It has been shown that the magnetic field activates matrix polymerization of such compositions and assists in structure formation of copolymers with minor cross-link density. The efficiency of the developed polymeric materials used for production of ultrathin contact lenses has been confirmed.
