Abstract
Creep and stress-relaxation of linear low-density polyethylene (LLDPE) crosslinked with β-irradiation was studied as a function of irradiation dose. It was shown that both storage modulus and α-relaxation are influenced by irradiation. An influence of relatively low gel content on stress relaxation was detected. However, the creep results showed an increase of the creep strain when the polymer is irradiated with a dose below 4 Megarad (MR) in comparison with a non-irradiated film. This increase corresponded to the disorientation in the amorphous phase, which takes place as a result of the film heating during irradiation. This disorientation was demonstrated by differential scanning calorimetry (DSC) and X-ray analysis. polyethylene Films, orientation, β-irradiation, crosslinking, stress relaxation, creep.
