POROUS FILM OF VINYLIDENE FLUORIDE RESIN AND METHOD FOR PRODUCING SAME |
摘要 |
<p>A porous film of a vinylidene fluoride resin having excellent hydrophilicity and a good balance among strength, ductility and water permeability is disclosed which is thus useful as a microfiltration membrane or a cell separator. The porous film is composed of a vinylidene fluoride copolymer obtained by copolymerizing 100 moles of a vinylidene fluoride monomer and 0.01-10.0 moles of a hydrophilic monomer having at least one group selected from epoxy groups, hydroxy groups, carboxy groups, ester groups, amide groups, and acid anhydride groups.</p> |
