Title:
POROUS FILM OF POLYVINYLIDENE FLUORIDE RESIN AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2020/138230
Kind Code:
A1
Abstract:
[Problem] To provide a porous film of a polyvinylidene fluoride resin wherein a small amount of a vinyl ether copolymer is used so that high hydrophilicity, high water permeability and excellent fouling resistance are obtained and the elution of the vinyl ether copolymer is prevented. [Solution] The porous film according to the present invention comprises a polyvinylidene fluoride resin serving as a base material and a vinyl ether copolymer, wherein the vinyl ether copolymer is a copolymer of an oxyethylene group-containing vinyl ether monomer with a hydrocarbon group-containing vinyl ether monomer.
