A comparative study of gamma irradiation of poly(ethylene-co-vinyl acetate) and poly(ethylene-co-vinyl acetate)/carbon black mixture

Sol-gel analysis results showed that both EVA and EVA/CB have tendencies to form a gel under gamma irradiation. As a result of FT-IR measurements, some oxidation products were observed in EVA and EVA/CB upon gamma irradiation. Thermal analysis experiments exhibited that the overall thermal stabilities of EVA and EVA/CB do not change, whereas, the amount of volatile products, formed during gamma irradiation, increase with irradiation dose both in EVA and EVA/CB.
