Quantitative analysis of FTIR Spectra of Acrylinitrile (AN) Methacrylate (MA) Copolymer

Abstract

FTIR spectroscopy is considered to be finger print technique to identify chemical structures of polymer. To prove this, FTIR spectra of unirradiated and irradiated ANMA are recorded under different conditions. The spectra show finger print absorption bands corresponding to both acrylonitrile and methacrylate groups. Radiation dose dependency on chemical structure of ANMA copolymer has been investigated by recording FTIR spectra at various radiation doses. Changes in intensity of some absorption bands are observed. Double integration methods are used to quantity the results. Based on the results chemical changes induced by gamma irradiation are identified.
