Description

The increase of the resistance of polyethylene to environmental stress-cracking by gamma-irradiation requires the exclusion of oxygen during irradiation, because a radiation oxidized surface layer would favor the formation of environmental stress-cracks. The exclusion of oxygen during irradiation can be eluded, if a small quantity of 1,2-polybutadiene is added to the polyethylene. The compound from polyethylene and 1,2-polybutadiene exhibits a much lower sensitivity to radiation oxidation, so that the resistance of that compound to environmental stress-cracking can be improved also by gamma irradiation in air.
