    Description / Table of Contents: Die Wärmeleitfähigkeit und die spezifische Warmekapazität von amorphem, nichtorientiertenl Polycarbonat wurden bei Temperaturen zwiscken 2 und 80 K gemessen. Die Temperaturabhängigkeit der Wärmeleitfahigkeit unterhalb von 20 K zeigt das Vorhandensein von Heterogenitaten an, deren spezifische Oberflache aus der mittleren freien Weglänge der Phononen abgeschätzt wird. Die heterogene Struktur bleibt nach Erwärmen des Materials äber die Glasäbergangstemperatur erhalten.
    Notes: The thermal condcutivity and specific heat of amorphous, non-oriented polycarbonate were measured in the temperature range between 2 and 80 K. The temperature dependence of the thermal conductivity below 20 K indicates the presence of heterogeneities. The specific surface of these heterogeneities is estimated from the phonon mean free path length. The heterogeneous structure is preserved when the material is heated above the glass transition temperature.
