| 摘 要： | 本文报道了用反相色谱法研究多嵌段聚醚氨酯与几种低分子化合物的相互作用,测定了表征相互作用的热力学参数。结果表明,由ESCA证明表面软段富集的聚醚氨酯的反相色谱行为主要决定于富集层与探针分子的相互作用;苯及几种烷烃和聚醚氨酯的偏摩尔混合热和它的溶度参数与软段组分的溶度参数差值有关。

| Abstract: | The inverse gas chromatography (IGC) was used to determine the heat of mixing of SPU with some organic compounds. The miscibility behavior of these systems and the surface properties of SPU was discussed based on this result. We also observed the phenomenon of soft segment enrichement on the surface of SPU film by IGC, and the results were compared with those obtained from the ESCA experiments. |
