Composite membrane having selective permeability and its preparation |
| abstract |
PURPOSE: To obtain the composite membrane having excellent selective permeability, at which the consolidation is little and the lowering of water permeability is little even if the operation is continued at high pressure while being contacted with a concentrated aqueous solution, by forming a thin film of the polymer consisting mainly of polybenzimidazolone containing a specified bonding unit on a porous carrier. n COPYRIGHT: (C)1979,JPO&Japio |
