contact lenses

The effect of a constant magnetic field on the polymerization of 2-hydroxyethyl methacrylate in the presence of a polyvinylpyrrolidone has been studied. The regularities of copolymer formation under different synthesis conditions, particularly depending on the magnetic field intensity, were identified. It has been shown that the magnetic field activates the complexation between the monomer and the polymer matrix, increasing the polymerization rate and the degree of structural order in the copolymers.

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.
