Polycarbonate polyol from sustainable feedstock for thermoplastic polyurethane |
| 초록 |
Carbon dioxide (CO2) is becoming increasingly important synthetic feedstock for chemicals and polymers, since it is abundant, low-cost, and non-toxic. Utilization of CO2 as a sustainable precursor for polyurethane (PU) is becoming a prime attention in polymer industry. In present study, commercially available polyol from CO2 and polyether polyol were successfully incorporated into thermoplastic polyurethanes (TPUs). The thermal and mechanical properties of the TPUs were compared with those of traditional TPUs from petroleum based polyols such as poly(tetrahydrofuran) and polypropylene glycol. The TPUs exhibited increased glass transition temperature and moduli with the CO2 based polyols, demonstrating harder and tougher elastomers in comparison with that from petroleum based polyols. These findings suggest that CO2 based TPUs will be promising alternative to conventional TPUs, enabling new applications of the ecofriendly material in high value added technologies. |
