“…A series of gamma-radiation cross-linking of polymer blends containing fresh or waste EPDM and PP was prepared by Zaharescu et al (13,14). They figured out the optimal dose range for the efficient cross-linking of all EPDM/PP blends to be 40-180 kGy.…”

“…Radiation cross linking becomes an effective tool to improve properties of polymeric materials (Ray Chowdhury and Sabharwal, 2011;Zaharescu et al, 1999). Radiation processing of polymers starts with gamma irradiations in industry and academia (Cleland et al, 2003;Machi, 1995).…”

“…Some studies on radiation processing (gamma) of polyolefins/EPDM have been reported (Zaharescu et al, 1999;Abdel-Aziz et al, 1992;Rizk et al, 2009). So far our knowledge is concern there is no reported literature on the influence of EB on crystallization and thermal stability of LDPE/EPDM blends.…”

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.

“…In blending of natural rubber with starch, radiation technology can be used as a tool to improve the adhesion between different phases in polymer blends and consequently the mechanical properties. It was established that radiation crosslinking of polymers improves their thermal, mechanical properties and it can be inducing reactive compatibilization [15][16][17][18]. The main advantages of the application of highenergy irradiation to polymer blends are the formation of strong bonds between macromolecules.…”
