PROBLEM TO BE SOLVED: To provide a silicone hydrogel containing n-alkylmethacrylamide and a contact lens produced from the same. Silicone hydrogels have an elastic modulus of about 965 to about 13,790 kPa (about 140 to about 2000 psi) and a water content of about 20 to about 50%, with at least one N-alkylmethacrylamide and at least one. It is formed from a reactive mixture containing two silicone-containing components. Silicone hydrogels may also contain hydrophilic components, cross-linking agents and toughening monomers. Silicone hydrogels are useful in the preparation of biomedical devices, ocular lenses, and contact lenses. [Selection diagram] None |
