The yields and spatial distribution of the products arising from the in source oxidation of 50 lm LDPE films induced by 60-Co gamma radiations and by 300 kev electrons have been investigated as a function of the dose rate. The dose rate was found to have a strong influence on the reaction, the hydro
Abstraet--The mechanism of the photo-oxidation of both low density and high density polyethylenes has been studied kinetically. The kinetics are consistent with the view that when substantial quantities of carbonyl compounds are present in the polymers by photolysis of thermally formed hydroperoxide
