Oxygen-17 labeled peroxy radicals were produced in polypropylene by electron-beam irradiation in the presence of enriched oxygen gas. Subsequent exposure to normal air did not reduce the extent of labeling. This finding suggest that the chain reactions RO/sub 2/ + RH ..-->.. ROOH + R and R + O/sub 2/ ..-->.. RO/sub 2/ are not important in this system.
