Characterization of PS-g-PI graft copolymer with two-dimensional liquid chromatography |
| 초록 |
Graft copolymer is a polymer having side chains composed of different monomers to that of the main chain. Since the backbone and graft chains are generally incompatible, most graft copolymers are multiphase materials exhibiting unique and interesting morphologies. Usually graft copolymers are characterized by size exclusion chromatography. But it is not enough to characterize synthetic graft copolymers because they often include side products. Two-dimensional liquid chromatography (2D-LC) is a combination of adequately selected two different LC separation methods and it can separate many species in synthetic polymer. In this study, we analyzed PS-g-PI graft copolymers which were synthesized by anionic polymerization. These polymers were characterized by two- dimensional liquid chromatography and confirmed by NMR. |
