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
The bonding of amorphous polystyrene (PS) and poly(2,6-dimethyl-1,4phenylene oxide) (PPO) was conducted over a broad range of time and temperatures, but always below the (bulk) glass transition temperature (T g ). Stress-strain properties developing at the symmetric (PS/PS and PPO/PPO) and asymmetri
