ABSTRACT Producing a surface modified skinless polyamide microporous filter membrane by providing a dope solution of a membrane forming polyamide polymer in a solvent system comprising a mixture of at least one solvent and one non-solvent for the polyamide polymer, and a surface modifying amount of a surface modifying agent having surface adsorption and/or sequestration effects which modifies the surfaces of the microporous filter membrane, combining the dope solution with additional non-solvent for the polyamide polymer for a time sufficient to precipitate said surface modified membrane from said dope solution, and casting the dope solution on a substrate. The filter membrane comprises a polyamide microporous membrane and a water-suspendable surface modifying agent having surface adsorption and/or sequestration effects which modifies the surfaces of the microporous membrane and is bonded to substantially all of the wetted surfaces of the membrane.
