FIELD: chemistry. ^ SUBSTANCE: silicone-hydrogel composition for soft contact lenses contains a silicone monomer N,O-bis(trimethylsilyl)acrylamide and 2-hydroxyethylmethacrylate, to which a water-soluble monomer N-vinyl-2-pyrrolidone or N,N-dimethylacrylamide is added to improve hydrophilic properties, as well as a cross-linking agent, such as ethylene glycol dimethacrylate or divinylbenzene, to improve hydrophilic properties, high content of water, high oxygen permeability, good elongation and optical transparency. ^ EFFECT: obtaining hydrophilic lenses with high content of water and high oxygen permeability. ^ 7 cl, 2 tbl |
