Abstract
The positron annihilation lifetime technique (PAL) has been applied to investigate the behaviour of the free volume (size and concentration) in butyl rubber (IIR) as a function of the concentration of semi-rein forcing furnace (SRF) carbon black. An attempt is to establish a corre lation between the macroscopic mechanical and electrical properties of rubber and the microscopic properties of the free volume holes. The d ependence of the size and the fraction of free volume in rubber on the concentration of SRF carbon black has been discussed on the basis of the free volume model.
