研究了４，４′－双叠氮芪－２，２′－二磺酸钠和戊二醛对聚乙烯吡咯烷酮（ＰＶＰ）、聚乙烯醇（ＰＶＡ）共混膜的交联及交联对共混膜分离恒沸点附近的乙醇／水混合物的影响．结果表明，膜的分离性质随着膜中ＰＶＰ含量的增加而改变；采用混合型交联剂对ＰＶＡ／ＰＶＰ共混膜交联能明显改善膜的选择性．
The effects of sodium 4,4’-bisazidostilbene-2,2’-disulfonate and glutaraldehyde on the crosslinking and cross-linking of polyvinylpyrrolidone (PVP) and polyvinyl alcohol (PVA) The effect of mixing the membrane on the ethanol / water mixture at constant boiling point is separated. The results showed that the separation properties of the films changed with the increase of the content of PVP in the films. Cross-linking of PVA / PVP blend films with mixed crosslinking agents could obviously improve the selectivity of the films.
