Synthesis and Characterization of Hyperbranched Poly(amicacid) and Polyimide via A2/B3 System |
| 초록 |
Aromatic polyimides are known as important high-performance polymers in various industrial fields. Hyperbranched polymers with 3-dimensional dendritic architecture have been received as attention due to their unique structure and physical and chemical properties. Therefore many kinds of hyperbranched polyimides have been investigated as novel dendritic macromolecules so far. In this study, we synthesis hyperbranched poly aminc acid and hyperbranched polyimides by condensation polymerization using conventional dianhydride and new type of triamine as core. By changing the monomer feed ratio and the method of monomer addition, we can control molecular weight and amine or anhydride terminated polyimides. The new polyimides were characterized by nuclear magnetic resonance (NNR), gel permeation chromatography (GPC), IR spectroscopy. |
