Dedoping of aqueous suspensions of PPY is followed at 75 and 89 °C by measurements of the conductivity, the pH and the pCl. This dedoping is characterized by the living of ions Cl - in water and the arrival of ions H +. This living is partially compensated by ions OH - going into particles.

Le dédopage de suspensions aqueuses de PPY est suivi à 75 et 89 °C par mesure de la conductivité, du pH et du pCl. Ce dédopage est caractérisé par le départ des dopants Cl - dans le milieu entraînant la formation d'ions H +. Ce départ est partiellement compensé par l'entrée d'ions OH - dans les particules.

Key words: conducting polymer -- polypyrrole -- dedoping -- electrical conductivity
