| 摘 要： | 对聚苯醚(PPO)进行了苯环溴代、甲基溴代以及胺交联,发现苯环溴代可提高O_2、N_2透过率(P),而选择性(α)基本不变。甲基溴代则相反,P降低、α有明显提高。调节两者比例可得到P、α兼优的O_2、N_2分离膜。甲基溴代后进一步胺交联可得到α更高、耐溶剂的膜材料。

| Abstract: | Poly(2,6-dimethylphenylene oxide) (PFO) has been brominated and crosslinked withammonia, ethylenediamine, m-phenylenediamine and hexamethylenetetramine. It was foundthat the oxygen permeability of the polymer membrane increased with the aryl-bromine con-tent in BrPPO and decreased with the benzyl-bromine content in BrPPO. NH_3-crosslinkingof BrPPO increased the oxygen permeability. Ethylenediamine-crosslinking of BrPPO increasedthe selectivity of oxygen over nitrogen significantly. Through crosslinking of benzyl-bromi-nated PPO a solvent resistant membrane with high selectivity of oxygen over nitrogen wasobtained. |
