Outline of Final Research Achievements

Free-radical polymerization is one of the most versatile polymerization techniques, and by introducing various types of reversible-deactivation reactions for the growing radicals, the polymerization system could be endowed with livingness to be called as the reversible-deactivation radical polymerization (RDRP). For a miniemulsion RDRP, the threshold diameters below which the polymerization rate deviates significantly from the corresponding bulk polymerization are shown quantitatively. On the basis of the present theory, it was found that the intermediate termination model applies for the dithiobenzoate-mediated RAFT polymerization of styrene.
