Structural Analysis of Gamma Induced Modification in Cr-39 Polymers

Meenakshi Choudhary, Sangeeta Prasher, Mukesh kumar

FTIR spectroscopy has been found to be useful technique in the study of chemical and structural changes occurring in polymeric systems due to irradiation. The present studies reports the structural changes in CR-39 polycarbonate irradiated to gamma radiations at different doses varying from 1KGy to 125KGy. The intensity of many functional groups has been found to decrease with increased dose indicating a release of some gases due to irradiation except at 5KGy dose. The G-values corresponding to some specific species have been calculated to study the reaction mechanism of polymer modificationsand the water content has been increased.
