✦ Synopsis

The a.c. electrical properties of graphitized carbon-black Ðlled rubbers were investigated in the temperature range 25È85¡C and in the frequency range 10È106 Hz. The volume fraction of the Ðller varied from 15 to 60%. The a.c. impedance was found to decrease dramatically with increasing Ðller content for volume fractions higher than 30%. A relaxation transition with an activation energy of 26É4È50 kJ/mol was observed only in the samples containing 45% and 60% of the Ðllers.
