| Outline of Final Research Achievements |
Construction of asymmetric templated polymerization systems requires the precise synthesis of helical polymers containing functional groups in the side chain. In this study, we developed the precise synthesis of new functionalized polyolefins through the post-modification. Olefin polymerizations of functional monomers using half-titanocene catalysts have been demonstrated, and the exclusive polymer modification (halogenation and cross-coupling reaction) of resultant polymers was able to tune the thermal and mechanical properties.

本研究成果では，ハーフチタンノセン触媒により精密合成した新規官能基化ポリオレフィンが，post-modificationにより様々な官能基化ポリマーに変換可能あることを示した。またポリマーの物理物性(熱物性，機械的特性等)は，変換された官能基に依存することが分かった。このポリマーの合成手法は様々な共重合体に応用が可能で汎用性が高いため，新規オレフィン系ポリマーの合成を可能とし，さらに自在に物理物性を調整できる技術となることが期待される。
