Abstract
There is described a process for producing a filtration membrane that is also capable of adsorbing proteins. The process comprises the steps of subjecting a porous polymeric substrate to a graft polymerization reaction with a polymerizable monomer under exposure to an ultraviolet radiation or an ionizing radiation and thereafter bringing an amino acid into contact with the resulting graft membrane for immobilization. The amino acid is contained in an amount of 0.01-1 millimole per gram of the porous polymeric substrate. The polymerizable monomer to be grafted onto the porous polymeric substrate contains an epoxy group.
