Low-density polyethylene and (ethylene-vinylacetate) blends in pure form were exposed to electron beam radiation at doses between (80 -150) kGy, at room temperature, in air. Postirradiation thermal aging was done through immersing the samples in hot water at 95°C. Mechanical properties and changes in chemical structure were determined after 1500 h. Accelerated oven aging test was carried out on thin films after immersing them in hot water for 1000 h. Heat aging treatment showed that the blends have a convenient thermal stability compared to polyethylene. Although elongation at break and tensile strength decreased after heat aging procedure, obviously, this reduction was lower in blended samples than that of pure PE. In all samples, hydroxyl and transvinylene unsaturated end groups were formed during heat aging in hot water. Formation of these groups was less in blends at doses between 80 -100 kGy, but was higher at 150 kGy than pure polyethylene.

“…According to Handlos (1979), the gel promoting efficiencies of these functional monomers depend on the initial 'G' values (crosslinking) value of monomers. In fact TMPTA possesses higher number of reactive double bonds than TAC (Waldron et al, 1985). R. Wiedenmann reports that there are so many unreacted double bonds in TAC-blended PE after irradiation (Wiedenmann, 1977).…”

The effect of blend composition and Electron Beam (EB) irradiation on the crystallization and thermal behavior of Low Density Polyethylene (LDPE)/Ethylene-Propylene-Diene elastomer (EPDM) blends had been studied. Melting temperatures were found to remain unchanged upon variation of blend composition as well as irradiation dose. But the degree of crystallinity and T c (crystallization temperature) were decreased with increase in EPDM content and EB dose. On the other hand, thermal stability (in terms of onset temperature and degradation temperature) and activation energy were increased with increase in EPDM content and irradiation dose. But the speed of degradation slowed down with increasing EPDM content and EB dose. Interestingly, once Trimethylolpropane Triacrylate (TMPTA) and Triallyl Cynuerate (TAC) were incorporated into the blends, the degrees of change of these properties were more in same direction upon irradiation. At higher irradiation dose properties were demoted due to chain scission.
