| Outline of Final Research Achievements |
A new synthetic method of structurally well-controlled symmetric polymers has been developed by photo-induced selective switching from living radical polymerization to radical coupling reaction. Polymers with controlled molecular weight were prepared by organotellurium-meidated living radical polymerization (TERP), and photolysis of the resulting polymers in the presence of dienes giving the coupling products in good to excellent yields. The high coupling efficiency can be ascribed to the high quantum yield of radical generation from organotellurium compounds. Structurally well-controlled telechelic polymers, block copolymers, and mid-chain functionalized polymers were successfully synthesized by this method.
