✦ Synopsis

The thermal diffusivity of several natural and synthetic rubber compounds was measured in the temperature range from 125 to 350 K with an automatic device. In every case, a step change has been found in the thermal diffusivity at the glass transition range. In partially crystalline elastomers, the thermal diffusivity shows a minimum, which agrees very well with the melting temperature of crystallites. Also, new estimations of thermal diffusivity of some elastomeric compounds are given at above and below the glass transition temperature.

The glass transition can be measured at different experimental conditions. Using spectroscopic methods at relative high frequency the a-relaxation is measured in the thermodynamic equilibrium. In the caloric case we call this phenomenon thermal relaxation transition (TRT). With a conventional differ

## Abstract The free‐volume theory of diffusion is used to predict the effect of the glass transition on the concentration dependence of the solvent self‐diffusion coefficient at constant temperature. The theoretical prediction is in agreement with experimental data. © 2003 Wiley Periodicals, Inc.
