Notes:
High-resolution NMR spectra was obtained for linear polyethylene powder irradiated by 60Co γ-rays in vacuo or in air. For the sample irradiated in vacuo, the spectra consist of two components having different line width. The narrow component was assigned to soluble molecules and the broad one to gel. When samples are irradiated in air, their spectra show no broad component. The GPC curves obtained for the samples irradiated in air shift to high elution counts (low molecular weight) upon increase of the irradiation dose. It is concluded that oxidative degradation is the predominant reaction in the sample irradiated in air.
