Synthesis and Characterization of watermelon-shaped Polystyrene via "Click Chemistry" |
| 초록 |
Synthesis of cyclic polymers has recently been attracting attention because cyclic structures are possible to have unprecedented properties such as high glass-transition temperatures and lower hydrodynamic volume. However, due to the synthetic difficulty and separation problem, synthesis of multicyclic polymers remains challenge. To overcome these problems, ATRP and “Click” reaction are introduced to synthesis of multicyclic polymers. “Click” reaction is highly efficient in cyclization of polymer due to high reactivity and low possibility to side reactions. Selective fractionation was used to separate cyclic and branched polymer. In this study, watermelon-shaped and branched polystyrene were synthesized simultaneously by intermolecular “Click” reaction between an azido-terminated polystyrene (star-PS-N3)6 and 6-alkynyl coupling agent in diluted solution. The structure of separated watermelon-shaped polystyrene was determined by MALDI-TOF MS, 1H NMR and FT-IR. |
