Determination of the Vinyl Acetate Content Using Thermogravimetry

Vinyl acetate, VAc, decomposes between 200 °C and 400 °C with loss of acetic acid. This degradation step can be used to calculate the VAc content in copolymers (EVA types) provided the sample shows no additional weight loss in this temperature range. This article shows the determination of the VAc content of several copolymers using thermogravimetry.
