| Abstract: | Lignin-based polyether polyurethane was synthesized by use of wheat straw oxygen-alkaline lignin to substitute for part of PEG,and its thermal performance and mechanical properties were primarily determined.The results showed that wheat straw oxygen-alkaline lignin could substitute part of PEG to react with MDI to synthesize polyurethane.The NCO index and lignin content had effect on the properties of lignin-based polyether polyurethane. |
| Keywords: | Wheat straw oxygen-alkaline lignin PEG MDI Polyurethane |
