при этом действие температуры проводят путем динамичного теплового нагрева с изменением температуры по экспоненциальному закону.1. A method of producing a polymer material for soft contact lenses by copolymerization of N-vinylpyrrolidone, methyl methacrylate and a crosslinking agent in the presence of a radical polymerization initiator under the influence of temperature, characterized in that difunctional methacrylic acid derivatives are used as a crosslinking agent and the copolymerization is carried out in the presence of 2-hydroxyethyl methacrylate when containing components, wt. %:
N-vinylpyrrolidone - 50-80
2-hydroxyethyl methacrylate - 10-40
Methyl methacrylate - 5-15
Crosslinking Agent - 0.05-5
The initiator of radical polymerization - 0.01-1
in this case, the action of temperature is carried out by dynamic thermal heating with a temperature change according to the exponential law.
