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 }, journal = {International Journal of Materials and Metallurgical Engineering}, volume = {6}, number = {11}, year = {2012}, pages = {1115 - 1118}, ee = {https://publications.waset.org/pdf/13488}, url = {https://publications.waset.org/vol/71}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 71, 2012}, }
