We have investigated, in terms of the Cohen-Turnbull theory, a relationship for polycarbonate (PC) glasses between average stress relaxation times, ( t o ) , and average free volume sizes, (q), obtained from positron annihilation lifetime spectroscopy. This examination suggests that the minimum free

The magnitude of the activation energy for diffusion, ED. is shown to be inversely dependent on the fractional free volume of the polymer above Tg. From the proportionality of ED above and below Tg, the magnitude of El, below T, is also inversely dependent on the free volume in that temperature rang
