Ftir Study for Structural Pattern Changes Due to Irradiation in Pe-Pp Block Copolymer

Abstract

In the present investigation, the FTIR has been used as a structural pattern recognition tool to study the effect of gamma irradiation on the PE-PP block copolymer. The polymer has been subjected to gamma irradiation from 100 to 500 Mrad dosages. Characterization of the polymer using XRD and FTIR was done both before irradiation and after irradiation in each step. FTIR study shows that the sample loses C -C stretching mode of vibration and gains C=C stretching mode of vibration after irradiation.
