제목 Living AnionicPolymerization 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. Living polymeric lithiums with low molecular weights(Mw=1,000~2,000g/mol) were used to investigate the chain-end functionalization yield with DPK and degree of coupling reaction by the attack of organolithium to the pyridine ring in the presence of TMEDA using GPC, 1H-NMR, 13C-NMR analysis.
