Summary

Measurements of thermal conductivity were made on polytetrafluoroethylene and polytrifluorochloroethylene which were crystallized by various heat treatments. The variation of thermal conductivity with the degree of crystallinity can be explained qualitatively in terms of the difference of the mean free path. An approximate calculation of the mean free path for the amorphous polytrifluorochloroethylene was made. The calculation gives the value of the mean free path which is very close to the atomic distances in the polymer molecule.

Zusammenfassung

Die thermische Leitfähigkeit von Polytetrafluoräthylen und Polytrifluorchloräthylen wurde an Proben gemessen, die durch verschiedene Wärmebehandlungen kristallisiert wurden. Die Änderung der thermischen Leitfähigkeit mit dem Kristallisationsgrad kann qualitativ durch die Unterschiede der mittleren freien Weglänge erklärt werden. Eine abschätzende Berechnung der mittleren freien Weglänge des Polytrifluorchloräthylens wurde durchgeführt. Die berechneten Werte liegen nahe an den Atomabständen der Polymermoleküle.
