Disclosed is a protein non-adsorptive semipermeable filtration membrane and a process for producing the same. Said membrane, which comprises an interpenetrating polymer network, is prepared from a casting solution comprising a prepolymer polymerizable upon contact with a coagulating liquid, a polymer that will not react readily with the prepolymer and that is substantially insoluble in said coagulating liquid, and solvent.

A self-supported substantially protein non-adsorptive, semipermeable filtration membrane consisting essentially of an interpenetrating polymer network prepared from a casting solution comprising (i) an isocyanate capped urethane prepolymer polymerizable upon contact with a coagulating liquid, (ii) a polymer that will not react readily with the prepolymer and that is substantially insoluble in said coagulating liquid, said polymer selected from the group acrylonitrile-vinyl chloride copolymer, polysulfone and cellulose acetate, and (iii) solvent.
