Process for the production of composite membranes |
| abstract |
A process for the production of a composite membrane consisting of a porous supporting membrane and a thin separating membrane. The separating membrane is produced on the surface of a carrier film (consisting essentially of a soluble polymer). The carrier film coated with the separating membrane is placed with its separating membrane side on a porous supporting membrane such that the separating membrane is between the supporting membrane and the carrier film. The carrier film is then dissolved. |
