AbstractEthylene polymers, including HDPE, Ziegler-Natta-catalyzed LLDPE (Z-N LLDPE), metallocene-catalyzed LLDPE (m-LLDPE), and LDPE were thermally treated by different procedures, that is, quenching, slow cooling, and thermal segregation. These PE samples, having different thermal histories, were then irradiated with various doses, that is, 0, 13, 35, and 70 Mrad, by gamma ray using a Co-60 radiation source. The melting and crystallization behaviors of these irradiated samples were studied by a differential scanning calorimeter (DSC). The effects of the thermal histories and irradiation on the polymers were evaluated by their melting temperatures (T), crystallization temperatures (T-c), and heat enthalpies (DeltaH) in the heating and cooling scans. The results indicated that irradiation affects the samples having different thermal histories in different ways. The effects of the dosage on each kind of sample are discussed.
