    Description / Table of Contents: Eine Gruppe neuer phenolischer Antioxidantien wurde synthetisiert und charakterisiert;ihr Einfluß auf die Polymerverarbeitung wurde an Polymerschmelzen bei wiederholter Extrusion unterucht. Die Äanderung des Schmelzflusses wurde gemessen und mit dem Verhalten bei Verwendung handelsüublicher Antioxidantien verglichen. Die untersuchten Verbindungen waren alle aus dem gleichen Phenylsegment aufgebaut, unterschieden sich aber in der Läange der para-Substituenten, die das Verhalten der Antioxidantien in Polymeren und somit ihre Wirkung entscheidend beeinflussen.
    Notes: A group of phenolic antioxidants was synthesized, characterized and the performance of these antioxidants in polymer processing was tested in the polymer melt by multiple extrusions. The change in melt flow was observed and compared with the change in melt flow by use of commercially available antioxidants. All the antioxidants examined had the same phenolic stabilization moiety but varied in the size of the substituents in the para-position of the aromatic ring. Increasing length of the side chain considerably influences the behaviour of the antioxidants in the polymer and thus their effectiveness.
