The invention discloses a method of producing the hyperfiltration membrane of amphiphilic copolymer modified polyvinylidene fluoride, comprising the following steps: 1) mixing polyvinylidene fluoride, poly (methyl methacrylate - monomethyl ether polyoxyethylene methyl methacrylate), additives, non-solvent and solvent to form the casting film solution; 2) making the casting film solution into the polyvinylidene fluoride membrane by using the film forming machine and then soaking in the coagulation bath; 3) conducting the posttreatment of hydrophilicity; 4)obtaining the hydrophilic polyvinylidene fluoride ultrafiltration membrane after cleaning and drying. The method is characterized in that the brush shape, chain ball shape or dumbbell shape amphiphilic copolymer are mixed with the polyvinylidene fluoride to produce the polyvinylidene fluoride hyperfiltration membrane with hydrophilicity, anti-pollution, large flux and high retention rate by adopting the solution phase conversion method. The method has the advantages that the obtained membrane is provided with dozens to hundreds nanometer of particular densified hydrogel surface layers, the contact angle of the membrane surface canbe reduced below 60 degrees and can be lowered to 0 degree within tens of seconds, the water flux can reach 1000L /m<2>/ h (0.1Mpa) or above, the retention rate of BSA can reach 90% or more and the recovery rate of water cleaning flux can reach 90% or higher.
