Synthesis of high molecular weight thermoplastic Lignin polymer through Step Growth urethane polymerization |
| 초록 |
The aim of this work is to investigate influence of reaction temperature on decomposition temperature of polymers and then to use the optimal reaction temperature to synthesized lignin-based polyurethane with different reaction times. The influence of reaction temperature and time on the thermal properties of different lignin-based polyurethanes were demonstrated by means of several characterization techniques such as Fourier transform infrared spectroscopy (FTIR) displays some strong peak 3364 cm-1 (NH) or 1673 cm-1 (NHCOO), dielectric analysis was defined Tg = 175 oC , and increased thermogravimetric analysis (TGA) was at Tid (2%) = 204 oC, moreover this aim studied was successfully increased molecular weight 724 000. The results obtained in this work showed the optimal reaction condition and confirm that lignin was incorporated in a polyurethane sample by chemical reaction with isocyanates, i.e., formation of urethane linkages. |
