    Description / Table of Contents: Neuartige photovernetzbare Polymethacrylate mit verbesserter thermischer Stabilität und Lösungsmittelbeständigkeit wurden hergestellt. In Copolymere aus Methylmethacrylat (MMA) oder Butylacrylat (BuA) mit p-Maleimidobenzoesäure (MBA) wurden photovernetzbare Methacrylfunktionen über die endständigen COOH-Gruppen eingebaut. Photofunktionelle Gruppen wurden über die Säurechloridroute und die Epoxy-Carboxy-Reaktion eingeführt. Die Photovernetzung wurde mittels UV-Strahlung bei 350 nm in Gegenwart eines Photoinitiators durchgeführt. Die Kinetik der Photohärtung wurde an einem Multiacrylat untersucht. Das Imid-modifizierte gehärtete Polyacrylat wies gegenüber dem nicht modifizierten Polymeren verbesserte thermische Stabilität und Lösungsmittelbeständigkeit auf.
    Notes: Novel photocrosslinkable polymethacrylate systems with enhanced thermal stability and solvent resistance were synthesized. Copolymers of methyl methacrylate (MMA) or butyl acrylate (BuA) with 4-maleimido benzoic acid (MBA) were synthesized and photocrosslinkable methacrylic functions were incorporated through the pendent COOH groups. Photofunctional groups were introduced by the acid chloride route and by the epoxy-carboxy reaction. Photocrosslinking was performed using UV radiation of 350 nm in the presence of a photo-initiator. The kinetics of photocuring was studied with a model multiacrylate. The imide-modified photocured acrylate polymer exhibited enhanced solvent resistance and thermal stability, compared with the unmodified polymer.
