Polymers doped with low‐molecular‐weight charge‐transfer (CT) complexes exhibit interesting electrical and photoelectrical properties. On the basis of the results of thermally stimulated depolarization (TSD) for polycarbonate (PC) doped with tetracyanoethylene‐ t ‐stilbene complex and its components, some information about the mechanism of mutual interaction was obtained. The measurements of stress relaxation, mechanical moduli, and ultimate strength in a wide temperature range fully confirmed the predicted behavior of PC s doped with CT complex and its components. Doping the PC with CT complex and its components lowers the glass‐transition temperature and increases the modulus in the range −60 to +60°C. The effects of doping on the mechanical properties of PC are explained in terms of α‐ and β‐relaxations.
