Effect of magnetic field on the structure formation and properties of hydroxyethylmethacrylate / polyvinylpyrrolidone copolymers

Abstract

The effect of a permanent magnetic field on the polymerization kinetics and structural parameters of a hydrogel network on the basis of 2-hydroxyethylmethacrylate with polyvinylpyrrolidone compositions has been investigated. It has been shown that the magnetic field activates matrix polymerization of mentioned compositions and assists in the structure formation of copolymers with a smaller crosslink density. The efficiency of the developed polymeric materials for production of ultrathin contact lenses "Glipox" has been confirmed
