| titleOfInvention |
Process for producing polyetheramide solutions, steam sterilizable membrane preparable by using the polyetheramide solutions, and process for preparing these membranes |
| abstract |
One or more dicarboxylic acid derivatives of the general formula I are known With one or more aromatic diamines of the general formula II and optionally polycondensing m-phenylenediamine in aprotic polar solvents.n n n By passing a sufficient amount of ammonia to neutralize the HCl formed into the polymer solution obtained after the end of the polycondensation and filtering off the resulting ammonium chloride, it is possible to produce neutral, salt-free and particularly storage-stable polyether amide solutions which can be further processed into membranes without isolating the polymer. Resulting membranes are steam sterilizable, chemically and thermally stable and show performance data in the area of good high-flux dialysis membranes.n n n Flat and hollow fiber membranes for ultrafiltration. |
