| Outline of Final Research Achievements |
In this study, we have developed the novel method to synthesize block copolymers of aliphatic polycarbonates (APC), which is obtained by the alternating copolymerization of epoxides with carbon dioxide, and vinyl polymers. The copolymerization with suitable chain transfer agents successfully gave the APCs with functional groups for the controlled radical polymerization of vinyl monomers. In addition, the atom tranfer radical polymerization and the reversible addition-fragmentation chain transfer polymerization of vinyl monomers were found to proceed to give the corresponding block copolymers of APCs and vinyl polymers.

| Academic Significance and Societal Importance of the Research Achievements |
APCは，化成品の原料として有効利用が望まれる二酸化炭素を原料とすることから，持続可能な社会に貢献する高分子材料として，学術・実用両方の観点から研究が展開されてきた．一方，ガラス転移温度や力学強度が低く，APCを実用化する上での障害となっている．本研究の成果によって得られたブロック共重合体には，APC単独では実現できない機能を発現することが予想され，APCを基盤とする材料開発に大きく貢献すると期待できる．
