Hydrophilic, soft and oxygen permeable copolymer compositions

摘要: A new composition of matter specially adapted for the production contact lenses, artificial eyes or other prosthetic devices. The has characteristics increased hydrophilicity, softness after hydration and oxygen permeability. is a solid copolymer comonomers consisting essentially about 15 to 65 parts by weight one more hydrophilic amide group containing monomers 10 75 copolymeric organosiloxane. Optionally, 0.1 at least property modifier, vinyl monomer such as methyl methacrylate, can be employed into copolymers. inventive material optionally transparent, translucent opaque depending on type, relative content used. In general, transparent suitable use in making lenses.
