| Research Abstract |
In this study, we investigated radical (co)polymerization of various 1,2-disubstituted cyclic vinyl monomers for possible construction of well-defined rigid and thermally-stable vinyl polymers. Cyclic olefins and cyclic styrene derivatives which have little homopolymerizability were copolymerized with electron-withdrawing monomers, N-substituted maleimides, to afford copolymers efficiently. Especially, when the copolymerization of these monomers were conducted in fluoroalcohol, the copolymerizability was enhanced to give predominantly alternating copolymers. The obtained copolymers possess relatively high Tg value and stiff main-chain. Furthermore, we succeeded in living/controlled radical (co)polymerizations of these cyclic vinyl monomers.
