| 摘 要： | 利用傅里叶变换红外光谱仪（FT-IR）研究了硬脂酰胺对热塑性聚氨酯（TPU）氢键化程度的影响。利用差示扫描量热仪（DSC）研究了硬脂酰胺对TPU等温结晶行为的影响，采用Avrami方程分析了TPU等温结晶过程，并计算出其结晶动力学参数。结果表明：加入硬脂酰胺后的TPU氢键化程度显著增大，结晶时间缩短，结晶速率提高。

| Abstract: | The effect of adding stearamide on the degree of hydrogen bonding of thermoplastic polyurethane (TPU) has been investigated by FT-IR. The effect of stearamide on the isothermal crystallization behavior of TPU was also studied by differential scanning calorimetry (DSC). The isothermal crystallization process was analyzed using the Avrami equation and the crystallization kinetic parameters were calculated. The results show that the extent of hydrogen bonding in TPU after adding stearamide is significantly increased, the crystallization time is shortened, and the crystallization rate is increased. |
