✦ Synopsis

The rate enhancing effects of aromatic solvents (1-fluoro-, 1-chloro-, l-bromonaphthalene and toluene) on the photo-and thermal sensitized polymerization of methyl methacrylate by azoinitiators at 25 Β° and 60 Β° respectively were investigated by measuring ko, k, and R, by means of rate, molecular weight and sector experiments. The rate of polymerization is affected by the nature and concentration of the solvent partly from the viscosity dependence of termination and partly from the solvent dependence of the propagation coefficient. A minor solvent effect on the rate of initiation was also noted.

The kinetics of the solution polymerization of methyl-methacrylate is characterized by a strong increase of viscosity up to 6 orders of magnitude and auto-acceleration of the reaction rate due to the gel-effect. This can lead to thermal and kinetic reactor instabilities. The kinetics were determined
