Рolymerization regularities, structure and properties of polyvinylpyrrolidone copolymers obtained in a permanent magnetic field

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. Copolymers synthesized under magnetic field conditions exhibit higher surface hardness, thermal resistance, permeability to low-molecular- weight substances, and hydrophilicity compared to polymers obtained without the application of a magnetic field. Synthesized copolymers are recommended for use in the production of contact lenses and implants.
