| Résumé | The oxidation rates and product distribution of a series of linear and branched polyethylene films have been studied when initiated by γ-irradiation. Branch groups in laboratory-synthesized samples ranged from ethyl to C₁₆H₃₃—and were at levels comparable with those found in commercial linear-low and low-density polyethylenes. In the complete absence of stabilizers and at the controlled rates of radical formation possible with γ-irradiation, all of the polyethylene samples oxidized at essentially the same rate to give the same mixture and distribution of products. The differences in oxidation rates previously attributed to the presence of tert. C---H groups at branch sites more probably originate from the effects of impurities, especially on photo- and thermal initiation processes. |
