Document Type and Number:
Japanese Patent JP3073778
Kind Code:
B2
Abstract:
A hydrophilic porous membrane based on a fluoropolymer, such as expanded polytetrafluoroethylene, is obtained by coating at least a portion of the interior of the membrane with a sufficient amount of a hydrophilic fluorine containing copolymer of a fluorine containing monomer and a non-fluorinated vinyl monomer containing a hydrophilic functional group. Examples of the fluorine containing monomer are vinylutene fluoride, vinyl fluoride, monochlorotrifluoro- or dichlorodifluoroethylene, hexafluoropropylene and tetrafluoroethylene. Examples of the non fluorinated vinyl monomer containing a hydrophilic functional group are acrylic acid, methacrylic acid, sulfonated styrene and vinyl alcohol.
