A novel synthetic route of 4-arm star-shaped Poly(methyl methacrylate) by ARGET-ATRP |
| 초록 |
In this study, a facile approach for the synthesis of 4-arm star-shaped Poly(methyl methacrylate) (PMMA) has been achieved successfully by Activators ReGenerated by Electron Transfer (ARGET) Atom Transfer Radical Polymerization (ATRP) with ppm level of copper (II) catalyst under activation of zerovalent copper as a reducing agent at room temperature and pentaerythritol tetrakis(2-bromoisobutyrate) as an initiator. The structure and molecular weight of the star-shaped polymer were investigated by means of FT-IR, 1H-NMR. GPC was employed to determine PDI of the star-shaped polymer. It was found that the formation of polymer brushes from the 4-arm initiator could be induced even though the catalyst amount was reduced to 50 ppm without loss of inherent control manner. |
