摘要：

The temperature dependence of the electrical conductivity (sigma) of six conjugated polyazomethines was studied in the temperature range (303-423 K). A plot of log(sigma) versus (1/T) reveals two regions with an inflection point at the glass transition temperature T-g of the polymers. Below T-g the conductivity is not very sensitive to change in temperature, while the sensitivity increases above T-g. This behavior is explained as a consequence of the effect of the different types of motions of the polymeric chains below and above T-g on the conductivity of the polymers.
