High performance and eco-friendly polyurethane using isosorbide as chain extender of hard segment part |
| 초록 |
Isosorbide-polyurethane(ISB-PU) series were successfully synthesized using poly(tetramethylene ether) glycol-methylene diphenyl diisocyanate (PTMG-MDI) as soft segment part, Isosorbide(ISB) as chain extender based on different molecular weight of pre-polymer. The ratio of soft segment and hard segment was used in the range of 9:1. The structures and properties of PUs were evaluated by fourier transform infrared spectroscopy(FT-IR), gel permeation chromatography(GPC), universal testing machine(UTM), differential scanning calorimerty(DSC) and thermogravimetric analysis(TGA). Compared using 1,4-BD as chain extender, ISB-PU exhibited high mechanical properties and heat-resisting property for high functional plastic applications in consumer/industrial and environment-friendly products fields. |
