Abstract
A preparation of dye-containing gas permeable silicon polymer and resin compositions are disclosed. Homopolymers and/or co-polymers of polysiloxane are formed in which a photoactive center substituent containing a dye is covalently bonded to the matrix structure thereby rendering the dye non-diffusible. These dye-silicone polymer compositions have particular utility in gas sensing fiber optics devices.
