Abstract of the Disclosure 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 percent of said organopolysiloxane urethane acrylate and 85 to 0 percent 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.
