Popis:	Transport of holes in poly$(p$-phenylene vinylene) has been studied as a function of frequency, temperature, dc bias, and polymer thickness. For such a low mobility material we demonstrate that the specific frequency dependence of the response reflects the wide distribution in transit times of the injected carriers due to dispersive transport. The dc mobility is shown to correspond to the average of this dispersion and follows the empirical $\mathrm{ln}({\ensuremath{\mu}}_{\mathrm{dc}})\ensuremath{\propto}\sqrt{E}$ law.
