Synthesis and Characterization of bipyridine-terminated Poly(Styrene-ran-Butadiene) |
| 초록 |
Poly(styrene-ran–butadiene) were synthesized by Living Anionic Polymerization using Styrene and butadiene as a monomer in the presence of sec-butyllithium. The Composition of poly(styrene-ran-butadiene) was controlled by feed ratio of [Styrene]/[Butadiene]. Di-2-pyridylketone was used as end-capping reagent. End-functionalized poly(styrene-ran-butadiene) were performed nucleophilic substitution reaction with di-2-pyridylketone. We synthesized low molecular weight(MW: 1000~1500 g/mol) copolymer in order to determine functionalization. The functionalized copolymers were investigated by 1H-NMR, 13C-NMR spectroscopy and FT-IR spectroscopy. Molecular weight distributions were measured using Gel Permeation Chromatography(GPC). |
