    Description / Table of Contents: Die anionische Polymerisation von Styrol mit Naphthalin-Natrium wurde mit einem Rotations-Scheiben-Reaktor durchgeführt. Die Art der Zerteilung der Polymerisationsmischung änderte sich von tropfenweise zu filamentartig und schließlich filmartig innerhalb weniger Minuten bei niedriger Umdrehungsgeschwindigkeit und großer Flußmenge. Bei hoher Umdrehungsgeschwindigkeit und kleiner Flußmenge wurde nur tropfenweise Aufteilung beobachtet, und ein Perlpolymerisat mit unimodaler Molekulargewichtsverteilung wurde erhalten. Das Polymer erlangt eine bimodale Verteilung, wenn die Polymerisation auf der rotierenden Scheibe abgebrochen wird. Die Ergebnisse werden durch die Annahme erklärt, daß sich nahe der Scheibenoberfläche eine hochviskose Schicht ausbildet.
    Notes: Anionic polymerization of styrene with sodium naphthalene was carried out using the rotating disk reactor. The mode of disintegration of the polymerization mixture changed from dropwise to filamentwise and finally to filmwise within a few minutes of reaction at low speed revolution and a large amount of flow. Under the condition of high speed revolution and a small amount of flow, only dropwise disintegration was observed and a beadlike polymer was obtained having a unimodal molecular weight distribution. The polymer was found to have a bimodal distribution when the polymerization was terminated on the rotating disk. These results are explained by assuming that a highly viscous layer was formed near the disk surface.
