The present invention relates to a method for producing light guide bodies and to their use in lighting units, for example for liquid crystal displays or for monitors. In particular, the present invention relates to a method for producing light guide bodies which have a thickness of at most 1 mm and contain at least 80 wt % of polymethyl methacrylate and no light-scattering constituents.

Method for producing light guide bodies and use thereof in lighting unit

Injection-molding materials comprised of polycarbonate can be processed into optically isotropic films in a chill roll extrusion method. The optically isotropic films for protecting data carriers (CD-ROMS) from becoming scratched, or they are used as supporting materials for the information layer.

Optically isotrophic polycarbonate films and a method for the production thereof

Injection-molding materials comprised of polycarbonate can be processed into optically isotropic films in a chill roll extrusion method. The optically isotropic films are used as covering films for protecting data carriers (CD-ROMS) from becoming scratched, or they are used as supporting materials for the information layer.
