Various conflicting reports in the literature regarding the effect of oxygen on the stability of vinyl acetate (VA) toward polymerization led us to reexamine this topic using both isothermal stability tests and quasi-adiabatic calorimetry. Both commercial VA stabilized with 5-20 ppm by weight of hyd

✦ Synopsis
Abstract
Vinyl acetate monomer and acrylic acid and its esters are stabilized with phenolic polymerization inhibitors. Oxygen is needed for these stabilizers to work effectively in acrylic monomers, but is not necessary for vinyl acetate monomer, and actually destabilizes it at elevated temperatures.
