    Description / Table of Contents: In Fortsetzung der vorangegangenen Arbeit wird die elektrische Leitfähigkeit in transversaler Richtung von mit 70 Gew.-% FEF-Ruß gefülltem Styrol-Butadien-Kautschuk im Detail diskutiert. Die Vordehnung ist ein Parameter, der das anomale Verhalten, das als Minimum in den elektrischen Leitfähigkeitskurven (σ vs T) erscheint, beeinflußt. Eine Korrelation zwischen dem Effekt der Vordehnung in der longitudinalen und transversalen Richtung wurde festgestellt.Die Dielektrizitätskonstante ∊′ und der dielektrische Verlustfaktor ∊″ in der transversalen Richtung sowie ihre Temperaturabhängigkeit wurden an den obengenannten vorgedehnten Proben bestimmt.
    Notes: Continuing the previous work, the electrical conductivity, σ, of 70 phr FEF/SBR pre-extended samples in the transverse direction is discussed in detail. The pre-extension is a parameter which affects the anomalous behaviour which appeared as a minimum in the electrical conductivity σ vs. T curves. A correlation between the effect of pre-extension on both the logitudinal and transverse direction has been done.The dielectric constant, ∊′ and the dielectric loss, ∊″, of the above mentioned pre-extended sample in the transverse direction and their dependence on temperature was observed.

    Description / Table of Contents: Die elektrische Leitfähigkeit von verschiedenen Kautschukmischungen (Styrol-Butadien-Kautschuk, Butadien-Kautschuk, Acrylnitril-Butadien-Kautschuk, Butylkautschuk und Naturkautschuk) wurde in Abhängigkeit von verschiedenen Längenausdehnungen untersucht. Jeder Kautschuktyp wurde separat mit 100 phr schnell spritzbarem Furnace-Ruß gemischt. Die Parameter des Modells von Polley und Boonstra wurden für ein Beispiel neu errechnet. Hierbei wurde eine gute Übereinstimmung erzielt.
    Notes: The electrical conduction was investigated in different rubber composites, subjected to various values of longitudinal extension. The study involves styrene-butadiene-rubber (SBR), butadiene-rubber (BR), acrylonitrile-butadiene-rubber (NBR), butyl-rubber (IIR), and natural rubber (NR). Each type was separately blended with 100 phr of fast extruding furnace black. The parameters of the model of Polley and Boonstra are recalculated for a specific example and good fitting is found.

    Effect of sulfur on the electrical conductivity of FEF-loaded SBR during swelling (1983)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 21 (1983), S. 3353-3360

    Notes: Following a series of experiments on the effect of different factors of the electrical conductivity of carbon-black-loaded styrene butadiene rubber, an attempt was made to study the effect on electrical conduction of changing the sulfur content. It was found that an optimum sulfur content leads to a swelling-resistant composite with good electrical insulation. This was done for dry as well as wet specimens of rubber.
