    Notes: A cell model for the prediction of temperature and concentration gradients in a nonisothermal tubular polymerization reactor at steady state is presented. Both radial and longitudinal gradients are considered. The complete molecular weight distribution is calculated as well as the leading moments of the distribution. The model is easily reduced to predict the performance of a plug-flow tubular reactor, batch reactor, and continuous stirred tank reactor (CSTR). The specific polymerization mechanism application consists of free-radical initiation, propagation, and combination termination.

    Description / Table of Contents: In this work the photolytic degradation of Poly-m-phenylene isophthalamide and its structural elements is treated. It is shown that the photoanilide rearrangement and its related side reactions are detrimental for the polymer. The prevention of the degradation of the polymer by application of systematically synthesized stabilizers as 2-(2′-hydroxy-5′-tert-butylphenyl)-benzotriazol-5-carbonic acid anilide is treated. The theory of light filter mechanism and mechanisms of energy transfer are discussed. Furthermore, a mechanism of energy dissipation of benzotriazole stabilizers is introduced.
    Notes: In der Arbeit wird der photolytische Abbau von Poly-(m-phenylen-isophthalamid) und dessen Strukturelementen behandelt. Es wird gezeigt, daß die Photoanilidumlagerung und die damit verbundenen Nebenreaktionen eine polymerschädigende Reaktion darstellen. Die Verhinderung des Abbaus des Polymeren durch Einsatz gezielt synthetisierter Stabilisatoren, wie 2-(2′-Hydroxy-5prime;-tert-butylphenyl)-benztriazol-carbonsäureanilid-(5), wird besprochen. Die Lichtfiltertheorie und Energieübertragungsmechanismen werden diskutiert. Außerdem wird ein Energiedissipationsmechanismus von Benztriazolstabilisatoren vorgestellt.
