摘要：

Ageing due to gamma radiation in air of a low density polyethylene, previously crosslinked by gamma-radiation under vacuum, is studied. The aim is to try to separate crosslinking and degradation phenomena which usually occur during irradiation in air. The effect of irradiation is investigated by means of solubility and swelling and calorimetric measurements, and stress-strain tensile tests. Gamma-radiation in air of the crosslinked polymer causes mainly oxidative degradation, the extent of which depends on irradiation dose rate.
