化学 聚己内酰胺 Membrane materials of polycaprolactam, copolyamide and cellulose are prepared as the column packing of liquid chromatography. Hydrophilicity and interfacial separation properties of them and the alloy (EC/CA) were studied and characterized by mean of the high performance liquid chromatography (HPLC). 本论文以聚己内酰胺及共聚酰胺类、纤维素类作为原料，研制出液相色谱柱填料，并采用高效液相色谱法对两类聚合物及其合金膜材料的亲水性和界面分离性能进行了研究、表征。 聚己内醯胺
