| 内容記述 | Polyurethane (PU) foams with various amounts of lignin and saccharides contained in polyols were prepared by changing the ratios of kraft lignin (KL) to molasses (ML) contents in polyethylene glycol (M_w=ca.200). Thermal and mechanical properties of the above polyurethanes (PU's) were investigated by differential scanning calorimetry (DSC), thermogravimetry (TG), simultaneous TG and Fourier-transform infrared spectrometry (TG-FTIR) and mechanical measurements. Glass transition temperatures (T_g's) of the PU's decreased from ca.115℃ to ca. 100℃ with increasing KL/ML ratio. However, thermal degradation temperatures (T_d's) increased with increasing KL/ML ratio from ca. 290℃ to ca. 300℃. The amount of thermal degradation products having characteristic functional groups changed according to the temperature. Compression strength of PU foams increased from ca. 650kPa to ca. 900 kPa with increasing KL contents. | |||||
