Provided is a production process for a semipermeable membrane having both semipermeability and strength and also provided is the semipermeable membrane. The process comprises the step of forming a liquid membrane from a membrane-forming solution comprising materials (A) to (C),
material (A) being a polymer having a repeating unit structure comprising one or more kinds of structural moieties selected from the group consisting of an amide group, an imide group, a sulfonyl group, and a heterocyclic ring,
material (B) being a good solvent for material (A),
material (C) being a salt, and
the step of removing the solvent from the liquid membrane. |
