Abstract
The gamma-radiation influence on the thermal stability of poly(3-hexad ecylthiophene) (PHDT) doped with FeCl3 in the surrounding atmosphere o f selected gases (O-2, SO2, NO2) and water vapour has been studied. Th e gamma-radiation effect decreases the rate of diffusion of the invest igated gases into the polymer mass as a consequence of crosslinking of the polymer system. The strong oxidant (NO,) stimulates the oxidative degradation of PHDT. The gamma-radiation effect causes a conversion o f the bivalent iron to trivalent.
