Living Anionic Polymerization of dipyridine chain-end functionalized polystyrene and polybutadiene |
| 초록 |
Dipyridine-terminated polystyrenes and polybutadienes were synthesized by the chain-end functionalization reaction of living polystyryllithium(PSLi) and (polybutadienyllithium)PBDLi with di(2-pyridyl)ketone(DPK) using a living anionic polymerization method in the Ar-glove box. DPK-terminated PBD exhibited much higher functionalization yield and less amount of coupling reaction compared to DPK-terminated PS. 86% functionalization yield with 9% degree of coupling was obtained when the PBDLi was added dropwise to DPK solution at room temperature. The functionalization yield was increased as the reaction temperature decreased but no LiCl effect was observed in this chain-end functionalization reaction with DPK. |
