|Outline of Final Research Achievements
We have developed and established a new copolymerization system based on a new concept, in which the stable dormant species were freely and reversibly converting different active species at the growing end of polymerization reaction to form one polymer chain. To realize the concept, the carbon-sulfur or -halogen bonds were employed as the dormant species, which can be activated into various active species and have conventionally been used only for the suppression of side reactions in living polymerizations. With this system, we have succeeded in developing unprecedented living copolymers that consisted of various types of the monomers via radical, anionic, and cationic polymerizations.
