Synthesis and comparison of isosorbide-based polyurethane using the molecular weight of polyols |
| 초록 |
Thermoplastic polyurethanes (TPUs) were successfully synthesized using condensation polymerization based on different molecular weights of polyol and methylene diphenyl diisocyanate for soft segments and isosorbide (ISB) chain extender as hard segments. An increase in the molecular weight of the polyol significantly affected the thermal properties. Various properties were evaluated by Fourier transform infrared spectroscopy (FT-IR), gel permeation chromatography (GPC), universal testing machine (UTM), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA). Polyurethanes using different molecular weights of polyols can be applied at various temperatures depending on the required properties. |
