Figure 2. The FTIR spectrum of Polyvinyl Acetate (PVAc). The PVAc absorbance exhibited strong acetate ester carbonyl bands at 1728 cm -1 (brown shaded peak). Other peaks are: 1433 cm-1, 1370cm-1, 1224 cm-1, and 1016 cm-1. The underline absorbance bands are used to identify & quantify the presence of PVAc
