Aninoic polymerization for dendrimer shaped poly(ethylene oxide)s |
| 초록 |
Dendritic poly(ethylene oxide)s were synthesized by anionic polymerization of ethylene oxide from three arm hydroxylated branching point at each PEO chain ends. The employed initiating system was composed of allyl alcohol as an initiator and t-BuOK as an electron transfer agent in THF. The initiating system was suitable for a “controlled/living” polymerization of ethylene oxide at 40 ℃. The sequences of reactions allowed us to prepare a dendrimer shaped PEO up to the higher generation. All generations are characterized by 1H NMR spectroscopy, GPC and MALDI-TOF. |
