POLYSILOXANE-BASED OPHTHALMIC DEVICE |
摘要 |
Shaped articles, particularly ophthalmic devices, can be fabricated from oxygen transmissive, hydrolytically stable, polysiloxane copolymers of readily prepared poly(organosiloxane) monomers having monourethane acrylate groups and copolymerizable ethylenically-unsaturated monomers. The ophthalmic devices comprise copolymers of compositions containing 15 to 100 per cent of said organopolysiloxane urethane acrylate and 85 to 0 per cent of copolymerizable ethylenically-unsaturated monomers. Ophthalmic devices which are fabricated from monourethane acrylates of polysiloxane alcohols have high oxygen permeability. A novel process is disclosed for the preparation of these polysiloxanes which have at least one urethane acrylate substituent. |
