    Notes: Summary Results are described of TSD- and TSP-measurements of Poly (Phenylquinoxaline) in dependence on the degree of annealing and on the polarizing field strength. Seven relaxations regions are investigated and discussed. Electronic and ionic space charge regions are observed and discussed in detail. It is shown that dielectric losses in polymers do not result from dipolar processes only, but also from translational motion of charge carriers.

    Description / Table of Contents: The differentiation of electron and ion charge carriers is of principal importance for explaining the electrical properties of high polymer solids. Experimental methods enabling differentiation between electron and ion charge carrier transport are summarized and estimated, particularly mass transport (mass spectroscopy, neutron activation analysis and tracer technique) as direct methods as well as “internal” electrical effects (d.c. characteristics and dielectric measurements) and “external” electrical effects (electrochemical cell, electrode conditions, pressure dependence of conductivity, photoelectric effects) as indirect methods. The results obtained with various high-ohmic polymer solids are summarized and discussed.
    Notes: für die Interpretation der elektrischen Eigenschaften polymerer Festkörper ist die Frage nach der elektronischen oder ionischen Natur der Ladungsträger von grundsätzlicher Bedeutung. Es werden experimentelle Methoden zusammengestellt und bewertet, die eine Unterscheidung zwischen einem elektronischen und einem ionischen Transport zulassen. Insbesondere sind dies die folgenden Methoden: Massetransport (Massenspektroskopie, Neutronenaktivie-rungsanalyse und Tracer-Technik) als direkte Verfahren und als indirekte Methoden die „inneren“ elektrischen Effekte (Gleichstrom-Charakteristika und dielektrische Messungen) und die „äßeren“ elektrischen Effekte (elektrochemische Zelle, Elektrodenbedingungen, Druckabhängigkeit des Leitwertes, photoelektrische Effekte). Die erhaltenen Ergebnisse werden für eine Reihe hochohmiger Polymerfestkörper zusammengestellt und diskutiert.
