titleOfInvention |
Composite semipermeable membrane and method for its production |
abstract |
An object of the present invention is to provide a composite semipermeable membrane which has a high permeation rate and a high salt removal performance and is excellent in stability of performance in long-term operation. The composite semipermeable membrane of the present invention comprises a support film comprising a substrate and a porous support layer, and a separating functional layer formed on the porous support layer, wherein the separating functional layer comprises a crosslinked polyamide and a hydrophilic polymer having an acidic group, In the functional layer, the molar equivalent of the amino group / the molar equivalent of the amide group is 0.18 or less. |
