What is On the Steady-state Approximation in Thermal Free Radical Frontal Polymerization about?
Frontal polymerization is a process in which a spatially localized reaction zone propagates into a monomer converting it into a polymer. We formulate a mathematical model of thermal free radical frontal polymerization involving a "ve-species reaction mechanism and justify its reduction to a four-species problem by combining the concentrations of two kinds of radicals, primary radicals and polymer radicals. We study the simpli"ed problem both numerically and analytically, and determine such important characteristics of the process as the propagation speed of the wave, the "nal temperature in the system, and the spatial distributions of all the species in the wave. We perform the analyses with the steady-state approximation (SSA) and without it, and reveal where the SSA solution breaks down. Speci"cally, the non-SSA solution predicts full monomer conversion and an adiabatic "nal system temperature, whereas the SSA solution predicts a less-than-adiabatic "nal temperature and incomplete conversion.
