Acrylic polymerizations are highly exothermic processes which must be carefully evaluated to ensure safe manufacture. In particular, failure to remove the heat of reaction can lead to runaway polymerizations, characterized by sudden and rapid increas

An extensive study of free-radical depropagation kinetics has been performed for several methacrylates at high temperatures in bulk and solution using a pulsed-laser technique. As expected from theory, the relative importance of depropagation on rate
