| 摘 要： | 分子量较高的癸二酸 二苯并 １８ 冠 ６共聚物可以制成具有一定韧性的薄膜，但该薄膜的透过性不好，当加入少量的水溶性聚合物聚乙烯吡咯烷酮（ＰＶＰ）后，薄膜的离子络合速度大幅度加快，并保持了对Ｋ＋较高选择性．同时研究了合金膜中ＰＶＰ的溶出量与温度及时间关系，以及合金膜的动态力学行为

| Abstract: | The high molecular weight condensation polymers(CEP|1) of dibenzo|18|crown|6(DB|18|C|6) with sebacic acid were good membrane|forming material,which had higher complex selectivities to K++,but the permeabilities of the membranes were low.The permeabilities can be improved greatly when CEP|1 was mixed with a little water|soluble poly(vinyl pyrrolidone)(PVP).The experimental result showed that CEP|1/PVP membranes have high complex rate,complex ability,complex selectivity to K++.The DMA spectra indicated that the modulus and tangent of the loss angle (tan ), were changed, therefore the CEP|1/PVP blends were partially compatible system. It has been found that the amount of PVP dissolved from CEP|1/PVP membrane were increased with temperature of water solution raising.= |
