Abstract
The long-term oxidative degradation for high density polyethylene (HDPE) irradiated with various ion-beams was studied. Such degradation was insignificant for low density polyethylene (LDPE) even if irradiation was carried out under the same condition as for HDPE. This is attributed to a hydroperoxide group as the initiator produced by the reaction of the allyl radical with oxygen. The relationship between the mechanical properties and the local transformation induced by ion-beam irradiation was investigated. It is seen that the depth profiles of the mechanical properties along the pathway of the injected ion correspond to that of the crosslinking induced in polyethylene.
