Ftir Analysis of Unirradiated and Irradiated Aaamps Copolymer

K. Rajendra Prasad and B. Sanjeeva Rao


Fourier transform infrared (FTIR) technique has been used to characterize chemical changes induced by gamma irradiation of acrylamide (AA)-2-acrylamide-2-methyl propane sulfonic acid (AMPS) (AAAMPS) copolymer. FTIR spectra observed for unirradiated AAAMPS copolymer has shown characteristic absorption bands at 3450, 2930, 1720, 1620, 1450, 1370, 1250, 1080 cm-1 positions, which characterize both AA and AMPS monomers. While on irradiation some of the absorption bands are found prone to gamma irradiation. Among them 3450, 1720, 1620 and 1050 cm-1 absorption bands are more prominent. As these bands represent sulfonic acid, ester carbonyl and amide carbonyl groups cleavage of these groups is anticipated on irradiation of the copolymer.
