Synthesis of poly(glycidyl azide-b-polystyrene) block copolymer via sequential ionic polymerization |
| 초록 |
Using a plug flow reactor system for anionic functionalization and controlled batch reactor system for cationic ring opening polymerization, poly(glycidyl azide-b-styrene) block copolymer was synthesized. Anionic polymerization of styrene was carried at -25℃ followed by anionic functionalization of polystyrene with epibromohydrin at -78℃. And Epichlorohydrin (ECH) was polymerized by using BF3-tripropylene glycol (TPG) complex via Active monomer mechanism. After ECH polymerization was complete, ω-epoxy terminated PS (EpPS) was introduced to the PECH solution in presence of BF3. The resulting polymer had bimodal distribution when the mole ratio of [EpPS]/[TPG] was more than 0.5 due to the PS-PS coupling reaction. Poly(glycidyl azide-b-styrene) (GAP-PS) was obtained by azidation reaction of PECH-PS with sodium azide. Thermal behavior of the PECH-PS block copolymers and GAP-PS block copolymer were also investigated. |
