    Description / Table of Contents: For a four-paramter reaction-mass transfer-model of the melt polycondensation the constants of polycondensation, thermolysis and diffusion were determined by means of experiments in thin layer polycondensation. Based on these constants the convectional mass transfer or efficient melt thickness in polycondensation systems under the conditions of compelled mixing can be estimated. This way of combining micro- with macrokinetics was tested experimentally in a 10 1 reactor with anchor agitator.
    Notes: Für ein vierparametriges Reaktions-Stofftransport-Modell der Schmelzepolykondensation wurden durch Polykondensationsversuche in dünner Schicht die Konstanten für Polykondensation, Thermolyse und Diffusion bestimmt. Mit diesen mikrokinetischen Konstanten lassen sich dann konvektiver Stofftransport bzw. effektive Schichtdicken in zwangsdurchmischten Polykondensationssystemen ermitteln. Dieser Weg der Kombination von Mikro- und Makrokinetik wurde experimentell in einem 10 1 Laborreaktor mit Ankerrührer überprüft.
