A copolymer suitable for hydrophilically modifying the surface of a porous fluoropolymer membrane is disclosed. Examples of such copolymers are the following: Also disclosed are a process for producing the copolymer, a method for hydrophilizing the porous fluoropolymer support, a hydrophilic porous fluoropolymer membrane prepared from the copolymer, and a method for filtering a fluid using the hydrophilic porous fluoropolymer membrane . |
