TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The reactive species is activated oxygen (preferred), oxygen containing species, halogen, atomic hydrogen and/or protons. The oxygen containing atmosphere is air.    TECHNOLOGY FOCUS - POLYMERS - Preferred Method: The step of exposing the silicone containing material to activated oxygen comprises exposing the material to an oxygen containing atmosphere while illuminating the material with ultraviolet radiation having a wavelength of 200-350 nm. The step of exposing the silicone containing material to the reactive species comprises exposing the material to the reactive species prior to the time the material is exposed to high energy ultraviolet radiation, where exposure of the material inhibits the formation of visible light absorbing species on it. The step of exposing the silicone containing material to the reactive species comprises exposing the material to the reactive species after the material has been exposed to the ultraviolet radiation, where the exposure reverses, at least in part, the formation of visible light absorbing species in the material. The silicone containing material has an absorption peak at 250-270 nm, and where the step of exposing the material to the reactive species comprises exposing the material for a period of time sufficient to reduce the intensity of that peak by at least 50%. The step of exposing the silicone containing material comprises exposing the material in air to ultraviolet radiation at 250-350 nm, where the amount of the radiation is 1000-3000 equivalent solar hours. The step of exposing the silicone containing material to the reactive species comprises exposing the material to an atmosphere which includes ozone. The method includes further step of: coating the silicone material onto a substrate after it has been exposed to the atmosphere containing an activated oxygen species; and coating the silicone material onto a substrate prior to the time it is exposed to the atmosphere containing an activated oxygen species. Preferred Components: The silicone containing material is a polyorganosiloxane. EXAMPLE - None given.
