WebMar 25, 2024 · The reaction kinetics during bulk free radical polymerization is still not fully understood. As the reaction proceeds, many parameters, including monomer/polymer fraction, radical concentration, viscosity, and temperature, change in a non-equilibrium manner. In this study, we investigate the bulk polymerization of methyl methacrylate, … WebAutoacceleration (gel effect, Trommsdorff–Norrish effect) is a dangerous reaction behavior that can occur in free-radical polymerization systems. It is due to the localized increases in viscosity of the polymerizing system that slow termination reactions.
