| Abstract: | Summary A quantitative method for the determination of vinyl mercaptoacetate (VMA) in poly(ethylene-co-vinyl alcohol-co-vinyl mercaptoacetate) (EVALSH) based on Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) was developed. A plot of relative absorbance values (A1736/A720) versus esterification degree in EVALSH samples determined by TGA analysis revealed a good linear relationship. |
