abstract |
The present invention has an object of providing a composition of a polymer porous membrane which is excellent in hydrophilicity, water permeability, mechanical strength, chemical durability, and low scale, and which is difficult to be eluted by a hydrophilizing agent. The present invention is a composition characterized by comprising a vinylidene fluoride-based resin and a copolymer (A) having a vinyl alcohol unit and a fluorine monomer unit. |
