    2017-4-27 · Fourier Transform Infrared Spectroscopy (FTIR) of polyacrylamide showed strong absorption at wave number 1655 cm-1 due to the presence of a primary amide band which is used to distinguish true polyacrylamide from the alternative polymerization product poly(βalanine) which has instead a secondary amide band at 1555 cm-1(4). The band for (N—H) stretching vibration appears at 3448 cm-1 of the NH2 group. Further, the absence of (C==C) band which usually appears at 1610 cm-1 proved that the acrylamide monomer has been completely converted to polyacrylamide and no residue of monomer is present in the polymer (9) studied the FTIR spectra of polyacrylamide, …
