- Abstract
The article presents a study which examined the effect of chain architecture on biaxial orientation as well as oxygen permeability of polypropylene film. It found that the stress response during stretching was dependent on the residual crystallinity in the same way for all three polymers. It also demonstrated a single one-to-one correlation between the oxygen permeability and the intensity of the dynamic mechanical β-relaxation.
