    Description / Table of Contents: Das Absorptionsspektrum von in Äthylbenzoat bei 200°C in Anwesenheit von Maleinsäureanhydrid (MA), Benzochinon (BQ) und Anthrachinon (AQ) abgebautem PVC wurde untersucht. Die Polyensequenzlängenverteilung wurde berechnet und festgestellt, daß die Bildung von Polyenen mit 6 konjugierten Doppelbindungen durch MA, nicht hingegen durch BQ und AQ reduziert wird. BQ und AQ verringern aber die Bildung von längeren Polyenen (n=8). Das Alterungsverhalten der abgebauten Polymerproben wird ebenfalls untersucht.
    Notes: Electronic absorption spectra of PVC degraded in ethyl benzoate at 200°C in presence of maleic anhydride (MA), benzoquinone (BQ) und anthraquinone (AQ), were studied. The distribution of polyene sequence length was calculated. It was observed that the rate of formation of polyenes having 6 conjugated double bonds was reduced in presence of MA. In case of BQ and AQ, no such inhibiting effect was observed. However, formation of polyenes having a higher number of double bonds (i. e. n=8) was reduced in the presence of these additives. The ageing behaviour of the degraded polymer samples was also investigated.
