    Description / Table of Contents: Summary The photodegradation of polymethylmethacrylate in chloroform and in 1,4-dioxane has been investigated in air in the presence of maleic anhydride. Maleic anhydride retards the photodegradation more effectively in 1.4-dioxane than in chloroform. The retardation of the degradation in 1.4-dioxane has been then interpreted as a direct sequence of the charge-transfer formation between the solvent and maleic anhydride.
    Notes: Zusammenfassung Der photochemische Abbau von Polymethylmethacrylat in Chloroform und in 1,4-Dioxan wurde in Anwesenheit von Maleinsäureanhydrid in Luftgegenwart untersucht. Maleinsäureanhydrid verzögert den Photoabbau des Polymeren in 1,4-Dioxan viel wirkungsvoller als in Chloroform. 1,4-Dioxan bildet mit Maleinsäureanhydrid einen Elektronen-Donator-Acceptor-Komplex, der für die Verzögerung des Abbaues verantwortlich ist.
