The diffusion coefficient for CO 2 in both unoriented and highly drawn films of polyethylene has been measured using Fourier transform i.r. spectroscopy and the ratio of the solubilities has also been found. In addition, scanning i.r. spectroscopy has been used to characterize the degree of orientation of the CO 2 molecules in the films.
