Abstract: The pressure effect on the kinetics of α-methylstyrene polymerization up to 5, 000kg/cm^2 and at various temperatures has been investigated. This polymerization system is characterized by the ceiling temperature, above which the formation of high polymer will not occur. The ratio of the rate constant of the propagation to that of the depropagation and the differences of activation parameters between them were calculated and discussed from the rate and thermodynamic equation derived by using the polymerization scheme with an accompanying depolymerization. The molecular weight of the polymer increased with pressure and the polymerization mechanism strongly depends on the nature of solvent.
