摘要：
The method of ESR tomography with a modulated gradient of a nonuniform magnetic field was used to obtain the spatial distribution of RO2 radicals in isotactic polypropylene exposed to gamma irradiation in air, and the parameter a = (k(ef)/D(O2))0.5 was determined. The possibility of predicting the change in the mechanical properties of polymers during radiation-induced oxidation is discussed.
