Inhibitors to prevent vinyl polymerization were selected rapidly and effectively by differential scanning calorimetry. The autopolymerization temperature (APT) and the relative polymerization rate constants were used to define the type and amount of inhibitor necessary to prevent polymerization of acrylic esters and acrylamides. The APT was also used to determine the amount of inhibitor in a vinyl monomer. The rate of polymerization and storage stability of vinyl monomers were determined by these methods.
