Abstract
(EN)
[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.
(FR)
Le problème décrit par la présente invention est de fournir un film poreux d'une résine de fluorure de polyvinylidène, une petite quantité d'un copolymère d'éther de vinyle étant utilisée de telle sorte qu'une hydrophilicité élevée, une perméabilité à l'eau élevée et une excellente résistance à l'encrassement sont obtenues et l'élution du copolymère d'éther de vinyle est empêchée. A cet effet, le film poreux selon la présente invention comprend une résine de fluorure de polyvinylidène servant de matériau de base et un copolymère d'éther vinylique, le copolymère d'éther vinylique étant un copolymère d'un monomère d'éther vinylique contenant un groupe oxyéthylène avec un monomère d'éther vinylique contenant un groupe hydrocarboné.
