Solvent resistant asymmetric integrally skinned membranes |
| abstract |
The invention relates to an asymmetric integrally skinned membrane comprising a polyimide and another polymer selected from the group consisting of polyvinylpyrrolidone, sulfonated polyetheretherketones and mixtures thereof. The membrane which is substantially insoluble in an organic solvent and substantially defect-free is useful as a vapor separation membrane. Methods for preparing asymmetric integrally skinned polyimide membranes are also disclosed. |
