    Description / Table of Contents: Die UV-vis-Spektren von reinen und dotierten Poly(methylmethacrylat)-Proben weisen keine drastischen Änderungen in der Lage der Absorptionsbanden auf. Daraus wird gefolgert, daß zwischen den Dotierungsmitteln und dem PMMA keine Wechselwirkungen auftreten. Die untersuchten Proben sind im Bereich von 800 bis 400 nm transparent, außer bei Dotierung mit Rhodamin B, das eine Absorptionsbande bei 555 nm hat. Diese Polymermaterialien eignen sich wegen ihrer starken Absorption im Bereich 400 bis 200 nm zur Verwendung als UV-Filter.
    Notes: The uv-vis spectra of pure and doped poly(methyl methacrylate) samples show no drastic changes in the position of the absorption bands. From this it is supposed that there is no interaction between the dopant and PMMA. The investigated samples are transparent in the region 800 to 400 nm, except in case of rhodamine B which shows an absorption band at 555 nm. These types of polymeric materials are suitable for use as uv filters due to their high absorption in the region 400 to 200 nm.
