The effect of gamma irradiation on micro-hardness of polymer blends of poly (ethyl methacrylate)(PEMA) and poly (ethylene oxide) (PEO) has been investigated to detect the radiation induced crosslinking. The blend system comprises a noncrystallizable polymer, PEMA and a crystallizable polymer, PEO. On irradiation, the overall hardness of the blend specimens for different dose levels infers occurrence of a crosslinking process. The radiation-induced crosslinking was greater for blends having lower concentration of PEO. However, increase in radiation dose causes softening of blend system due to radiation induced scissioning of the chains<\/p>\r\n","references":"[1] Mutsumasa K., Wiwik P.& Akhtar S., Rheological, thermal, and mechanical properties of poly(ethylene naphthalate)\/poly(ethylene\r\nterephthalate) blends, J. of Macromole.
