Solvent resistant asymmetric integrally skinned membranes |
摘要 |
There is provided 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 can be useful as a separation membrane. Methods for preparing asymmetric integrally skinned polyimide membranes are also disclosed
