PROCESS FOR THE MANUFACTURE OF SEMI-PERMEABLE MEMBRANES, OBTAINED MEMBRANES AND THEIR APPLICATION |
| abstract |
The process consists in treating with hot water, at a temperature of 50 to 100 degrees C, a wet porous membrane prepared by wet casting of an acrylonitrile polymer containing 40 to 100 mole% of acrylonitrile, then in treating with a plasma the resulting membrane. The semi-permeable membrane obtained can be used very advantageously for the separation and concentration of substance by reverse osmosis and ultrafiltration. |
