The permeability and diffusion coefficient of gases such as N2, O2 and CO2 through two polymeric membranes of poly(α-alkyl β,L-aspartate)s (PAALA-n) were determined by the “time-lag” method. One of these membranes was crystalline (PAALA-1) and the other one was amorphous (PAALA-6). The comparison of the obtained result for both membranes is addressed by the calculation of the so called configurational entropy. The study has been done in the range of temperatures 20 °C to 70 °C.
