| 摘要 |
A thin film composite (TFC) semipermeable membrane on a semiporous substrate is produced by an interfacial polymerization reaction between (1) an aqueous phase comprising a blend of water soluble and water dispersable compounds, (the latter being a chlorine or other oxidant neutralizer which protects the resulting semipermeable membrane from short term damage by chlorine or other oxidants) and (2) an organic phase comprising polyfunctional crosslinking reagents capable of reacting and/or polymerizing with one or more of the ingredients of said aqueous phase.
