| titleOfInvention | Composite semipermeable membrane |
| abstract | A composite semipermeable membrane using a copolymer of a vinyl cyanide-based monomer and an aromatic vinyl-based monomer as a porous support has a salt removal performance even under a high pressure condition of 4.0 MPa or more. Provide a composite semipermeable membrane that can be maintained (composite semipermeable membrane with high pressure resistance). The composite semipermeable membrane of the present invention is a composite semipermeable membrane comprising a support film having a substrate and a porous support on the substrate, and a separation functional layer on the porous support. hand, The porous support contains a copolymer of a vinyl cyanide-based monomer and an aromatic vinyl-based monomer, and has a depth of 5 μm from the surface on the separation functional layer side in a cross section of the porous support. The composite semipermeable membrane having a resin ratio in the range of 45% or more. [Selection diagram] Fig. 1 |
