Living anionic polymerization of styrene derivatives containing adamantylimino group |
| 초록 |
The anionic polymerization of N-(1-adamantyl)-N-4-vinylbenzylideneamine (1) and N-(2-adamantyl)-N-4-vinylbenzylideneamine (2) was performed using various initiators in THF at −78 °C for 1 h to investigate the effects of adamantyl groups on the polymerization behaviors and thermal properties of the resulting polymers. The well-defined poly(1) and poly(2) with predictable molecular weights and narrow molecular weight distributions were successfully obtained, indicating that the bulky adamantyl groups effectively protected the carbon−nitrogen double bond from the nucleophilic attack of the initiators and the propagating chain ends. The resulting poly(1) and poly(2) showed significantly high glass transition temperatures (Tg) at 257 and 209 °C due to the bulky and stiff adamantyl substituents. |
