摘要：

Two-cycle creep recovery penetration measurements at 150 degree C are used to determine the viscoelastic parameters for irradiated low density and linear low density polyethylenes, pure and with 0. 5% antioxidant. The amplitudes and the time factors of each cycle are calculated using the mechanical model expression. From the differences between the creep parameters of the first and the second cycle, the contribution of the nonelastic component is considered. The efficiency of radiation crosslinking of different systems is discussed on the base of the corresponding compliances.
