Microporous membranes from polypropylene. |
| 摘要 |
<p>Microporous polypropylene membrane or hollow fibers is formed from a melt blend of 5 to 20 weight percent polypropylene and a solvent. The melt blend is shaped and cooled to effect solid phase separation of the polypropylene from the blend. The solvent is separated from the polypropylene by extraction and the porous polypropylene is dried under restraint to prevent shrinkage.</p> |
