Abstract
The permeability variations of carbon dioxide, oxygen, and nitrogen th rough isotactic polypropylene, heterophasic ethylene-propylene (E-P) c opolymers, and polyethylene films were measured during photooxidation using polychromatic light at 60 degrees C in air. For polypropylene-ba sed samples the permeability decreases with increasing photooxidation, whereas for polyethylene and an elastomeric fraction from a heteropha sic E-P copolymer an increase in permeability with photooxidation is o bserved.
