Method of preparing mmembranes from blends of polyetherimide and polyimide polymers. |
| 摘要 |
<p>Improved fluid separation membranes are prepared from the blends of polyetherimide with phenylindane containing polyimides, wherein the amount of phenylindane containing polyimide in the blend is low. The present invention provides for highly anisotropic membranes particularly useful for gas separation applications and for preparation of composite membranes thereof.</p> |
