POROUS FILM OF VINYLIDENE FLUORIDE RESIN AND METHOD FOR PRODUCING SAME |
| 摘要 |
<p>A porous membrane of vinylidene fluoride resin excellent in hydrophilicity and having a good balance among strength, elongation and water permeation rate, which is thus useful as a microfiltration membrane or a separator of battery. The porous membrane is formed from a copolymer of 100 mols of a vinylidene fluoride monomer and 0.01 - 10.0 mols of a hydrophilic monomer having at least one species of hydrophilic group selected from epoxy group, hydroxy group, carboxy group, ester group, amide group and acid anhydride group.</p> |
