Development of Novel Polymerization System

在本研究中，我们通过各种共价键，如C-S和C-X （X：卤素）键，研究了可转换中间体的并发混合聚合。通过将C-S键作为休眠物种，我们发现阳离子和自由基共聚同时进行，形成由阳离子和自由基聚合段组成的多嵌段型共聚物。此外，我们还实现了从阴离子聚合到以C-X键为休眠物种的自由基聚合的机理转变。

In the present study, we investigated concurrent mixed polymerizations by interconvertible intermediates via various covalent bond, such as C–S and C-X (X: halogen) bonds. By using C-S bond as the dormant species, we found that concurrent cationic and radical copolymerization prodeeded well in a living fashion to form multiblock-type copolymer consinsting of cationically-and radically-polymerized segments. Furthermore, we achieved that mechanistic transformation from anionic polymerization to radical one with C–X bond as the dormant species.
