| titleOfInvention | USEFUL COMPOSITION TO PREPARE A SEMIPERMEABLE MEMBRANE OF POLISULPHONE, PROCESS TO PREPARE THE MEMBRANE, SEMIPERMEABLE MEMBRANE OF POLISULPHONE, DIALYZER, EXTRACORPOREOUS BLOOD TREATMENT DEVICE AND LIQUID SEPARATION DEVICE. |
| abstract | Compositions are described which are useful for producing a homogeneous semipermeable membrane, the composition comprising (1) a polysulfone compound, (2) a solvent, such as sulfolane, antipyrine, deltavalerolactam, ftalat or diethyl, and mixtures thereof, and (3) a non-solvent, such as poly (ethylene glycol), di (ethylene glycol), tri (ethylene glycol), glycerol, and mixtures thereof. Methods for the manufacture of semi-permeable membranes are described by homogeneously mixing the composition of the polysulfone compound, solvent, and non-solvent, melting the composition, and melt spinning the molten composition. In addition, homogeneous, semi-permeable, fusion spun membranes, useful for liquid separation processes, are described, such as, but not limited to, microfiltration, ultrafiltration, dialysis and reverse osmosis; process to prepare the membrane; a dialyzer, an extracorporeal blood device and a separation device comprising the membrane. |
