## Abstract Anomalies in the temperature dependence of the conductivity of BF~4~^−^ doped polypyrrole were observed in cyclic measurements at temperatures between 250 K and 310 K. The anomalies were accompanied by endothermic effects in differential scanning calorimetry and are interpreted as being
