Determination of the vinyl mercaptoacetate content in poly(ethylene co vinyl acetate co vinyl mercaptoacetate) (EVASH) by TGA analysis and FTIR spectroscopy

摘要

A new method has been developed for determining the esterification degree (ED) of EVASH copolymers by Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). A plot of absorbance values (A(1736) - A(720)) versus ED in EVASH samples determined by TGA analysis revealed a good linear relationship. [References: 14]
