Kinetics Of

In this paper, we followed the kinetics of methyl methacrylate (MMA) through a novel fluorescence method. The real-time measurement results show that in the regime of very low monomer contents, such as a solution containing 0.1 wt% of MMA with respect to water and with the anionic surfactant of sodium dodecyl sulphate (SDS), the kinetic of the miniemulsion could be followed by this embed fluorescence method. The processes of changing from emulsion to miniemulsion with different amount of surfactant and cosurfactant also have been monitored.

Free Radical Initiator

Methyl methacrylate has been polymerized in the presence of poly(methyl methacrylate) by using a free-radical initiator. The efficiency of the initiator is shown to be independent of the viscosity. At high viscosities, chain termination was influenced by the rate of translational diffusion of the polymer radicals. The dependence of the polymerization rate on viscosity is less than that predicted by a simple kinetic scheme. It appears that only those radicals which are above a certain size have their chain termination reactions controlled by the solution viscosity. This limiting size decreases as the viscosity increases.
