    Description / Table of Contents: Veränderungen der Molekulargewichte und der Molekulargewichtsverteilung von PVC, das in Gegenwart von Maleinsäureanhydrid, Benzochinon oder Anthrachinon abgebaut wurde, wurden durch Gelchromatographie untersucht. Ketten-Spaltungs- und Vernetzungsreaktionen waren durch den M̄w und M̄n-Wert zu erkennen. In Gegenwart von Anthrachinon waren Vernetzungsreaktionen vorherrschend.
    Notes: The changes in molecular weight and molecular weight distribution of PVC degraded in presence of maleic anhydride, benzoquinone and anthraquinone were studied by gel permeation chromatography. Chain scission and crosslinking reactions were indicated on the basis of M̄n and M̄w of degraded samples. Crosslinking was predominant when degradation was carried out in presence of anthraquinone.
