Synthesis and characterization of thermoplastic polyurethane based on eco-friendly isosorbide chain extender |
| 초록 |
Thermoplastic polyurethanes (TPUs) were successfully synthesized using in-situ condensation polymerization based on poly(tetramethylene ether) glycol-methylene diphenyl diisocyanate (PTMG-MDI) as soft blocks and eco-friendly isosorbide (ISB) chain extender as hard blocks. The differences in molecular weight (650, 1000, 2000g/mol) of polyol significantly affected the mechanical properties because the lower molecular weight of polyol increases the number of urethane groups. Various properties were evaluated by fourier transform infrared spectroscopy (FT-IR), gel permeation chromatography (GPC), universal testing machine (UTM), differential scanning calorimetry (DSC). ISB-PU exhibited high mechanical properties for high functional plastic applications in eco-friendly products fields. |
