    Notes: Summary The influence of static and cyclic compression on the temperature dependence of the electrical conductivity σ(T) of 100 phr FEF black-loaded rubber vulcanizates (SBR, NR, IIR, BR and NBR) has been studied. It was found that σ increases with static pressure for all rubber vulcanizates. The temperature coefficient of conductivity proved to be negative; its maximum value α ranges between −0.1 and −0.01 deg−1 depending upon the applied stress and type of rubber vulcanizate. The pressure coefficient of conductivity γ at room temperature varies with the static pressure from 0.78 to 0.04 (kg/cm2)−1. Menwhile, a was found to decrease with the number and stress amplitude of the cyclic compressions, while α increases with the number of compression cycles.

    Notes: The influence of dynamic cyclic extension on the electrcal conductivity (σ) of 100 parts FEF carbon black loaded rubber (NR and SBR) vulcanizates was studied. The conductivity showed an initial rapid decrease with increasing cyclic strain amplitude, indicating a probable breakdown of the carbon black structure, owing to the masking of carbon particles by insulating rubber layers.The conduction mechanisms in these composites in terms of both the number of strain cycles and the strain amplitude were also studied. In addition, the temperature coefficient of conductivity was calculated for different amplitudes. It was greatly affected by the magnitude of the strain amplitude.

    Notes: The penetration of organic solvent and its influence on the electrical conductance of pre-extended styrene butadiene (SBR), butadiene (BR), acrylonitrile butadiene (NBR), butyl (IIR), and natural (NR) rubbers are investigated. A model is proposed for a process by which it is possible to estimate the separation distance between carbon black particles (or aggregates) and its dependence on the extent of penetration of the liquid. An empirical formula is suggested to describe the variation of the conductance of rubber composites with swelling time in terms of the interspacing distance.

    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.
