    Description / Table of Contents: The reactions of radicals formed by 60Co irradiation in poly(methyl methacrylate) and copolymers of methyl methacrylate and methacrylic acid (70/30) have been investigated. Further radical formation was found to occur with increasing temperature, amounting to 10% of the radical formation by γ-radiolysis. The validity of the model of a wide distribution of reaction rates is discussed.
    Notes: Die Reaktionen der Radikale, die durch 60Co-Strahlung in Polymethylmethacrylat und in Copolymerisaten aus Methylmethacrylat und Methacrylsäure (70/30 Masse-%) erzeugt werden, wurden untersucht. Es wird nachgewiesen, daß durch Temperaturerhöhung weitere Radikale erzeugt werden, die 10% der durch γ-Radiolyse gebildeten Radikalkonzentrationen erreichen. Die Anwendbarkeit des Modells der breiten Verteilung der Reaktionsgeschwindigkeiten wird diskutiert.

    Description / Table of Contents: Based on ESR data the effect of annealing and oxygen on the radical reactions in γ-irradiated copolymers of methacrylic acid methyl ester and methacrylic acid is compared with the effect in poly(methyl methacrylate).
    Notes: Der Einfluß von Temperung und Sauerstoff auf die Radikalreaktionen in γ-bestrahlten Copolymeren aus Methacrylsäuremethylester und Methacrylsäure werden im Vergleich zu denjenigen in Polymethylmethacrylat ausgehend von ESR-Messungen diskutiert.
