Abstract
A quantitative method for the determination of vinyl mercaptoacetate ( VMA) in poly(ethylene-co-vinyl alcohol-co-vinyl mercaptoacetate) (EVAL SH) based on Fourier transform infrared spectroscopy (FTIR) and thermo gravimetric analysis (TGA) was developed. A plot of relative absorbanc e values (A(1736) / A(720)) versus esterification degree in EVALSH sam ples determined by TGA analysis revealed a good linear relationship.
