| titleOfInvention | Melt-spun polysulfone semipermeable membranes and methods for making the same |
| abstract | The invention particularly relates to solvents such as (1) polysulfone compounds, (2) sulfolane, antipyrine, δ-valerolactam, diethylphthalate and mixtures thereof and (3) poly (ethylene glycol), di (ethylene glycol) And compositions useful for making uniform semipermeable membranes, including nonsolvents such as tri (ethylene glycol), glycerol, and mixtures thereof. A second aspect of the present invention relates to a method of making a semipermeable membrane by uniformly mixing a mixture of a polysulfone compound, a solvent and a nonsolvent, melting the composition and melt-spinning the molten composition. All. A third aspect of the invention includes a homogeneous meltspun semipermeable membrane useful for liquid separation methods such as microfiltration, ultrafiltration, dialysis and reverse osmosis. |
