    Notes: Abstract Two ethylene-vinyl alcohol copolymers (Eval E and Eval F with about 45% and 25% of ethylene respectively) have been irradiated in air in the dose range 0–200 Mrad. The irradiated samples show both crosslinking and degradation; the former effect is more relevant in the copolymer with a larger content of polyethylene. Calorimetric results show that both the crystalline and the amorphous phases are involved in the reactions initiated by the irradiation.

    Notes: Abstract Stress-strain and dynamic-mechanical tests were performed on two ethylene-vinyl alcohol copolymers (Eval E and Eval F, with about 45% and 25% of ethylene respectively) irradiated in air. The experimental results, in agreement with the solubility and calorimetric results previously reported [1], show that both crosslinking and chain scission are present, and that a decrease in the degree of crystallinity with the irradiation dose occurs.
