Abstract :
Polarization phenomena associated with amorphous polycarbonate have been investigated by thermally stimulated current spectroscopy. The relaxation modes are characteristic of its thermodynamic history. The existence of compensation laws reveal the presence of local order in the amorphous phase. The existence of domains of some 20 to 40 Å is postulated, using the granular model of G.S.Y. Yeh (1972)
