Abstract: Formed articles, such as medical devices, can be made of an acrylic-based polymer material, which contains at least one polyalkyl(meth)acrylate. A method can be used for the UV disinfection and/or sterilization of the formed articles, including disinfection and/or sterilization of the inner surface of the formed article. The method for UV sterilization involves exposure of the outer surface of the formed article with UV radiation at a wavelength in the range of 260 nm to 300 nm, wherein the acrylic-based polymer material has a transmittance of at least 10%, averaged over the wavelength range from 260 nm to 300 nm, measured in accordance with ISO 13468-2 at a thickness of 3 mm.

Abstract: Light scattering polymeric compositions have improved scattering efficiency and improved mechanical properties. The compositions include a polymeric matrix material and at least two different kinds of scattering particles uniformly dispersed therein.

Abstract: Heat resistant brittle films can be made from impact-modified poly(meth)acrylimide, and forgery prevention labels can contain the heat resistant brittle films. The films can be advantageously prepared by extrusion and, depending on the desired purpose, can be designed to be transparent, translucent, or entirely non-transparent, e.g., white. Ideally, the brittle films and the forgery prevention labels containing the brittle films have no intended break points such as slits, perforation, etc.

Abstract: A light emitting element includes edge-lit luminaires of transparent light guiding material having an increased resistance against UV-light and high temperatures. The light emitting element can be advantageously employed as a light source in outdoor applications such as traffic signs, street lights, advertising panels, outdoor illumination means or in exterior vehicle lighting.
